Rebound damping of fork

Hydraulic rebound damping determines the reaction when the fork is rebound. Remove the protecting cap [1].

By turning the adjusting screw [2], the degree of damping of the rebound can be adjusted. Turn the knob clockwise to increase damping, turn it counterclockwise to reduce damping during rebounding.

STANDARD ADJUSTMENT:

– turn adjusting screw clockwise as far as it will go

– turn it back by as many clicks as are specified for the relevant type of fork

Compression damping of fork

Hydraulic compression damping determines the reaction when the fork is compressed. The degree of compression can be adjusted with adjusting screws at the bottom of the fork legs.

Turn the screw [3] clockwise to increase damping, turn it counterclockwise to reduce damping during compression.


– turn adjusting screw clockwise as far as it will go

– turn it back by as many clicks as are specified for the relevant type of fork



Damping action during compression of shock absorber

The shock absorber on the SX models can synchronize the compression damping in the low and high-speed range separately (Dual Compression Control).

Low and high speed refers to the movement of the shock absorber during compression and not to the speed of the motorcycle.

The low and high-speed technology overlaps.

The low-speed setting is primarily for slow to normal shock absorber compression rates.The high-speed setting is effective at fast compression rates.Turning in a clockwise direction will increase the damping, turning counterclockwise will decrease the damping.

STANDARD LOW-SPEED SETTING:

– Turn the adjusting screw [4] to the limit in a clockwise direction using a screwdriver .

– Unscrew the respective number of clicks for the specific type of shock absorber in a counterclockwise direction.



The damping unit of the shock absorber is filled with high-compression nitrogen. Never try to take the shock absorber apart or to do any maintenance work yourself. Severe injuries could be the result.

Never unscrew the black screw [5] connection (24mm).

STANDARD HIGH-SPEED SETTING:

– Turn the adjusting screw [6] to the limit in a counterclockwise direction using a box wrench.

GENERAL TIPS AND WARNINGS FOR STARTING THE MOTORCYCLE

»

Instructions for your first ride

– Make sure the work for the "pre-delivery inspection" was performed by your authorized KTM workshop. The DELIVERY CER-

TIFICATE and SERVICE MANUAL will be handed over when you pick up your vehicle.

– Thoroughly read the whole instruction manual before starting for your first tour.

– Familiarize yourself with the controls.

– Adjust the clutch lever, the hand brake lever and the foot brake pedal to the most comfortable position.

– Get used to handling the motorcycle on an empty parking lot or open space, before going for a longer ride. Also try to ride as slowly as possible while standing upright, to improve your feeling for the vehicle.

– Do not drive along off-road trails which go beyond your ability and experience.

– Hold the handlebar with both hands and leave your feet on the foot rests while driving.

– Remove your foot from the foot brake lever when you are not braking. If the foot brake lever is not released the brake pads rub continuously and the braking system is overheated.

– Do not make any alterations to the motorcycle and always use

ORIGINAL KTM SPARE PARTS. Spare parts from other manufacturers can impair the safety of the motorcycle.

– Motorcycles are sensitive to alterations in the distribution of weight. If you are taking luggage with you, it should be secured as close as possible to the middle of the vehicle; distribute the weight evenly between the front and the rear wheel. Never exceed the maximum permissible laden weight and the axle weights. The maximum permissible laden weight is made up of the following components:

- Motorcycle ready for operation and tank full

- Luggage

- Driver and passenger with protective clothing and helmet.

– Pay attention to running-in procedure.

– Wear suitable clothing when driving a motorcycle. smart KTM drivers always wear a helmet, boots, gloves, and a jacket, regardless of whether driving all day or just go for a short ride.

– Do not drive after having consumed alcohol.

– Only use accessory parts recommended by KTM.

– The front and rear wheel are allowed to be fitted only with tires that have the same profile type.

– Be sure to check the spoke tension after 30 minutes' running time.

The spoke tension will decrease quickly on new wheels. If you continue to drive with loose spokes, the spokes may crack and lead to unstable handling (see "Checking the spoke tension").

– Adjust your driving speed to the conditions and your driving skills.

– Drive carefully on unknown roads or in unknown territory.

– When driving off-road, always have a friend on a second motorcycle to keep you company, so that you can help each other should difficulties arise.

– Replace the helmet visor or goggle glasses early enough. When light shines directly on a scratched visor or goggles, you will be practically blind.

– Never leave your motorcycle without supervision as long as the engine is running.

– The Above Models were designed and built for one person only

- no additional passenger allowed!

– Neither do these models meet the applicable statutory regulations and safety standards. Using them on public roads, highways, freeways, etc. is against the law.

– When riding your motorcycle, please bear in mind that other people may feel molested by excessive noise.

9

Running in

Even very precisely machined sections of engine components have rougher surfaces than components which have been sliding across one another for quite some time. Therefore, every engine needs to be broken in. For this reason, during its first 500 kilometers (300 miles) or 5 hours the engine must not be revved up to its performance limits.

Apply low but changing loads for running-in.

Do not drive at full load for the first 500 kilometers (300 miles) or 5 hours!

DRIVING INSTRUCTIONS

»

What you should check before each start

When you start off, the motorcycle must be in a perfect technical condition.

For safety reasons, you should make it a habit to perform an overall check of your motorcycle before each start.

The following checks should be performed:

1 CHECK TRANSMISSION OIL LEVEL

Too little transmission oil leads to premature wear and will ultimately destroy gear wheels and parts of the shift mechanism.

2 FUEL

Check that there is sufficient fuel in the tank; when closing the filler cap, check that the tank venting hose is free of kinks.

3 CHAIN

A loose chain was fall off the chain wheels; an extremely worn chain may tear, and insufficient lubrication may result in unnecessary wear of the chain and chain wheels.

4 TIRES

Check for damaged tires. Tires showing cuts or dents must be replaced.

The tread depth must comply with the legal regulations. Also check the air pressure. Insufficient tread and incorrect air pressure deteriorate the driving performance.

5 BRAKES

Check correct functioning of the braking system. Verify that there is sufficient brake fluid in the reservoir. The reservoirs have been designed in such a way that brake fluid does not need to be refilled even when the brake pads are worn. If the level of brake fluid falls below the minimum value, this indicates a leak in the braking system or completely worn out brake pads. Arrange for the braking system to be checked by an authorized KTM dealer, as complete failure of the braking system can be expected.

Also check the state of the brake hose and the thickness of the brake linings.

Check free travel of the hand brake lever and foot brake lever.

If the resistance in the hand brake lever or foot brake pedal feels „spongy“

(too much give), this is an indication that something is wrong with the brake system. Don’t ride your motorcycle anymore without first having the brake system looked over by a KTM dealer.

6 CABLES

Check correct adjustment and easy running of all control cables.

FLUID

Check the level of cooling fluid when the engine is cold.


»

Starting when the engine is cold

1 Open fuel tap

2 Put the gear in neutral

3 Activate cold-starting aid (choke)

4 Leave throttle closed or open it no more than 1/3 and kick down kickstarter vigorously all the way.

– For starting always put on your motorcycle boots to avoid injuries. You could slip off the kickstarter or the motor could kick back and fling your foot upwards.

– Forcefully kick the kickstarter down the whole way and do not open the throttle. A kickstart with too little momentum and an opened throttle increases the kicking back risk.

– Check for power transmission at temperatures below 0°C (32°F) before you actuate the kickstarter. If you depress the kickstarter without feeling any resistance, power is not being transmitted. This could cause injuries.

– Do not start the engine and allow it to idle in a closed area. Exhaust fumes are poisonous and can cause loss of consciousness and death. Always provide adequate ventilation while the engine is running.

Do not ride your motorcycle with full load and do not rev up the engine when cold. Since the piston warms up and expands faster than the water cooled cylinder, this might cause engine damage. Always let engine idle until warm or drive it warm at low r.p.m. speeds.

NOTE:

The highly inflammable components in modern fuels volatilize if left standing for longer periods of time. If the motorcycle has not been used for over

1 week, the fuel should be drained from the float chamber. The engine will start up immediately if the float chamber is filled with fresh, ignitable fuel

11

Starting when the engine is warm

1 Open fuel tap

2 Put the gear in neutral

3 Open throttle to 1/2 and kick down kickstarter vigorously

What to do when the engine is „flooded“

1 Close fuel tap

2 Start engine with full throttle. If necessary, unscrew spark plug and dry it.

3 Once the engine is running, open fuel tap again.

Starting off

Pull the clutch lever. Put the engine into first gear, slowly release the clutch lever and accelerate at the same time.

– Before you start off, check that the main or side stand has been swung right up to the top. If the stand drags on the floor, you may lose control of your motorcycle.

– Before starting for an off-road tour, it is recommended to additionally secure the side stand with the rubber band on the air filter box.

Shifting/Riding

You are now in first gear, referred to as the drive or uphill gear.

Depending on the conditions (hill size, etc.), you can shift to a higher gear. Turn down the throttle, at the same time pull the clutch lever in and shift to the next higher gear. Let the clutch lever go again and open the throttle. If you turned on the choke, make sure you turn it off again as soon as engine is warm.

When you reach full speed through opening the throttle all the way, turn throttle back to 3/4; the speed hardly decreases although the engine will use less gas. Only give as much gas as the engine can handle. Through quick and high revving of throttle, the gas consumption will increase. When shifting down, use the brakes if necessary and turn down at the same time. Pull the clutch lever and shift down to the next lower gear. Let the clutch lever go slowly and open the throttle or shift down again.

– After falling with the motorcycle, check all its functions thoroughly before using it again.

– A twisted handlebar must always be replaced. Do not adjust the handlebar, it will lose stability.

Motorcycle engines produce a great amount of heat while running.

The engine, exhaust pipe, muffler, brake rotors, and shock absorbers can become very hot. Do not touch any of these parts after starting the motorcycle, and take care to park it where pedestrians are not likely to touch it and get burned.

– Close the fuel tap when leaving your vehicle. Otherwise the carburetor may get flooded and fuel will enter the engine.

– Never park your motorcycle in places where there exist fire hazards due to dry grass or other easily flammable materials.

Refueling, fuel

Unleaded premium gasoline RON 95 mixed with high grade two stroke oil.

Mixture ratio 125 SX: 1:40

Mixture ratio 250 SX: 1:60

Fuel and engine oil should only be mixed immediately before use.

KTM recommends Motorex Cross Power 2T.

– High rpm rates when the engine is cold have an adverse effect on the life of your engine. We recommend you run the engine in a moderate rpm range for a few miles giving it a chance to warm up. After that no further precautions in this respect need to be taken.

– Never have the throttle wide open when changing down to a lower gear. The engine will overrev, damaging the valves. In addition, the rear wheel will block so that the motorcycle can easily get out of control.

– If the engine runs without throttle during longer downhill travel, the engine should be accelerated occasionally to ensure that it is supplied with sufficient lubricant which is mixed in the fuel.

– In the event that, while riding on your motorcycle, you notice any unusual operation-related noise, stop immediately, turn the engine off, and contact an authorized KTM dealer.

Braking

Turn off the gas and apply the hand and foot brakes at the same time. When driving on sandy, wet or slippery ground, use mainly the rear wheel brake. Always brake with feeling, blocking wheels can cause you to skid or fall. Also change down to lower gears depending on your speed.

Gasoline is highly flammable and poisonous. Extreme caution should be used when handling gasoline. Do not refuel the motorcycle near open flames or burning cigarettes. Always switch off the engine before refueling. Be careful not to spill gasoline on the engine or exhaust pipe while the engine is hot. Wipe up spills promptly.

If gasoline is swallowed or splashed in the eyes, seek a doctor’s advice immediately.

– Only use premium-grade gasoline ROZ 98 respectively 95 mixed with high-grade two-stroke engine oil. Other types of gasoline can cause engine failure.

– Do not use premixed two-stroke oils, oils for outboard engines or normal engine oil to prepare the mixture.

– Do not use gasoline and oil mixtures that are older than one week. The lubrication properties of some two-stroke oils can deteriorate very rapidly.

– Only use known brands of high-grade 2-stroke engine oil (i.e.

Motorex Cross Power 2T).

– Never mix synthetic oils and mineral oils.

– Not enough oil or low-grade oil can cause erosion of the piston. when Using too much oil, the engine may start smoking and foul the spark plug.

– If your motorcycle is equipped with a catalytic converter, always keep in mind that leaded fuel will destroy the catalytic converter.

– Fuel expands when its temperature rises. Therefore do not fill the tank to the top. (see fig.)

– In case of rain, after washing the motorcycle, after rides through water and in case of rides on wet off-road tracks, humid or dirty brake discs can delay the braking effect. The brakes must be pulled until they are dry or clean.

– Rides on salt-strewed or dirty roads can also delay the braking effect. The brakes must be pulled until they are clean.

– Dirty brake discs cause increased tear of brake pads and brake discs.

– When you brake, the brake discs, brake pads, brake caliper and brake fluid heat up. The hotter these parts get, the weaker the breaking effect. In extreme cases, the entire braking system can fail.

– If the resistance in the hand brake lever or foot brake pedal feels “spongy” (too much give), this is an indication that something is wrong with the brake system. Don’t ride your motorcycle anymore without first having the brake system looked over by a KTM dealer.

Stopping and parking

Close the throttle and apply the hand and foot brake simultaneously. Be especially careful when you apply the brakes on sandy, wet or slick surfaces. Always apply the brakes intuitively, locked wheels can cause the bike to skid or crash. Shift down to a lower gear to match your speed. Always apply the brakes before you enter a curve.

MAINTENANCE WORK ON CHASSIS AND ENGINE

»

Maintenance and adjusting work marked with an asterisk * requires expert skills and technical know-how. For your own safety, always have such work performed by a specialized KTM dealer where your motorcycle will be optimally serviced by appropriately qualified, skilled staff.

– If using a power washer, do not point the water jet at the electric components, plugs, cables, bearings, carburetor, etc. The high pressure will cause water to penetrate into the components and can cause them to malfunction or lead to premature wear.

– When transporting your KTM, ensure that it is held upright with restraining straps or other mechanical fastening devices and that the fuel tap is in the OFF position - if the motorcycle should fall over, no fuel can leak from the carburetor or fuel tank

– Only use special screws with an appropriate thread length supplied by KTM to fix the spoilers on the tank. Using other screws or longer screws can cause leaks in the tank through which fuel can flow out.

– Do not use toothed washers or spring rings with the engine fastening screws, as these work into the frame parts and keep working loose. Instead, use self-locking nuts.

– If you unscrewed any screwed connections with self-locking nuts, they must be replaced when mounting. If no self-locking nuts are available, apply Loctite 243 to the thread. The screws and nuts must be replaced if the thread is damaged.

– All screws and nuts must be tightened to the specified torque figures using a torque wrench. If screws or nuts are not adequately tightened, they can become loose and cause the motorcycle to go out of control while you drive. Tightening the screws and nuts too tightly can damage the thread and components.

– Let your motorcycle cool down before beginning any maintenance work in order to avoid getting burned.

– Dispose of oils, fatty matters, filters, fuels, washing detergents, etc. properly.

– Under no circumstances may used oil be disposed of in the sewage system or in the open countryside. 1 liter of used oil contaminates 1,000,000 liters of water.

Changing the spring preloading of the shock absorber

The spring preload can be changed by turning the adjusting ring [1]. For this purpose, you should dismount the shock absorber and clean it thoroughly.

NOTE:

– Before changing the spring preload note down the basic setting, e.g. how many threads are visible above the adjusting ring.

– One rotation of the adjusting ring [1] changes the spring pretension by approximately 1.00 mm (0.04 in).

Loosen the clamping screw [2] and use the hook wrench contained in the vehicle tool set to turn the adjusting ring as desired. Turning it counterclockwise will reduce the preload, turning it clockwise will increase the preload.

After readjusting the clamping screw [2], tighten it to 8 Nm (6 ft.lb)

Pivot bearing

The pivot bearing [3] for PDS suspension struts at the swinging fork is Tefloncoated and must not be lubricated with either grease or other lubricants. Grease and other lubricants cause the Teflon coat to dissolve, whereby the bearing’s lifecycle will be reduced dramatically.

When cleaning your bike with a high-pressure cleaner, do not aim the highpressure spray directly at the pivot bearing.

A

Basic suspension setup for the weight of the driver

To achieve maximum handling performance and to prevent the fork, shock absorber, swing arm and frame from being damaged, the basic setup of the suspension components must be suitable for your weight. At delivery, KTM's offroad motorcycles are set to accommodate a driver weighing 75 bis 85 kg

(wearing full protective clothing). If your weight exceeds or falls short of this range, you will need to adjust the basic setup for the suspension components accordingly. Minor deviations in weight can be compensated by adjusting the spring preload. Different springs must be installed for larger deviations.

B

Checking the shock absorber and spring

You can establish whether or not the shock absorber spring is suitable for your weight by checking the riding sag. The static slag must be correctly adjusted before the riding sag can be determined.

Determining the static sag of the shock absorber

The static sag should be as close as possible to 35 mm. Deviations of more than 2 mm can strongly influence the motorcycle's performance.

Procedure:

– Jack up the motorcycle until the rear wheel no longer touches the ground.

– Measure the vertical distance between the rear wheel axle and a fixed point

(e.g. a mark on the side cover) and write it down as dimension A.

– Place the motorcycle on the ground again.

– Ask a helper to hold the motorcycle in vertical position.

– Measure the distance between the rear axle and the fixed point again to establish dimension B.

– The static sag is the difference between dimensions A and B.

Static sag . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .35 mm

If the static sag is lower, the spring preload of the shock absorber must be increased, if the static sag is reduced, the spring preload must be higher. See chapter "Changing the spring preload of the shock absorber."

Determining the riding sag of the shock absorber

– Have a helper hold the motorcycle while you sit on the bike in a normal seating position (feet on the footrests) wearing full protective clothing and bounce up and down a few times to allow the rear wheel suspension to become level.

– Stay on the bike and have another person measure the distance between the same two points and write it down as dimension C.

– The riding sag is the difference between dimensions A and C.

EXAMPLE:

Motorcycle jacked up (dimension A) . . . . . . . . . . . . . . . . . . . . . .600 mm

Riding sag . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .100 mm

The riding sag should lie between 95 and 105 mm.

If the riding sag is less than 95 mm, the spring is too hard (the spring rate is too high). If the riding sag is more than 105 mm, the spring is too soft (the spring rate is too low).

The spring rate is written on the outside of the spring (e.g. 63-250). The type number of the shock absorber is embossed on the front of the shock absorber.The

illustrations show which spring should be installed. The standard spring is shown in bold print .

After installing a different spring, readjust the static sag to 35 mm (± 2 mm).

According to our experience, the damping rate of the compression stage can remain unchanged. The damping rate of the rebound stage can be reduced by a few clicks for a softer spring or increased by a few clicks for a harder spring.


»

Checking the basic setup of the telescopic fork

The precise riding sag of the telescopic fork cannot be determined for various reasons. Similar to the shock absorber, smaller deviations in your weight can be compensated by adjusting the spring preload. However, if your telescopic fork bumps frequently (hard end stop during compression), you should install harder fork springs to avoid damaging the telescopic fork and frame.

Changing the spring preload on the telescopic fork

The telescopic forks for these models must be partly disassembled to adjust the spring preload (see WP manual). Pretension spacers are available in heights of 1.5, 2.5, 5 and 10 mm (see spare parts catalog). The fork springs may not be pretensioned by more than 20 mm.

NOTE:

WP precisely adjusts the spring pressure by inserting pretension spacers.

Fluctuations in production are compensated with pretension spacers in various heights. This can cause the fork springs in the fork legs to have different degrees of pretension. Fork springs and pretension spacers should always stay together.

Replacing fork springs

If you weigh less than 75 kg or more than 85 kg, you should install the respective fork springs. The correct spring rate is shown in the illustrations. The standard spring is shown in bold print. The type number of the telescopic fork is embossed on the inside of the fork leg axle passage.

If you are uncertain which spring to use, contact your KTM workshop.

According to our experience, the damping rate of the compression stage can remain unchanged. The damping rate of the rebound stage can be reduced by a few clicks for a softer spring or increased by a few clicks for a harder spring.

Breather plug front fork

After every 5 hours of use for competitive racing, slacken the breather plugs [1] a few turns in order to relieve excess pressure from the inside of the fork. To do this, place the motorcycle on a stand with the front wheel lifted off the ground. When riding the motorcycle mainly on the road, it will suffice to have this job performed in the course of the periodical maintenance service.

17

Excessive pressure in the interior of the fork can cause leaks in the fork. If your fork is leaking, it is recommended to open the breather plugs before having the seals replaced.

Cleaning the dust sleeves of the telescopic fork

The dust-protection bellows [2] are to remove dust and coarse dirt particles from the fork tube. However, after some time, dirt may also get in behind the dust-protection bellows. If this dirt is not removed, the oil sealing rings located behind it may start to leak.

Use a screwdriver to lift the dust-protection bellows out of the outer tubes and slide them downward.

2

Clean the dust-protection bellows, outer tubes, and fork tubes thoroughly, and oil them thoroughly with Universal oil spray (Motorex Joker 440) or engine oil. Then, push the dust-protection bellows into the outer tubes by hand.

No oil may reach the front tire or the brake disks since this would considerably reduce the tire's road grip and the braking effect of the front brake.

Changing the fork offset (caster

The fork offset [A] in the SX models (center fork legs - center steering head angle) can be set to either 18 or 20 mm. This allows you to optimize the handling to match the race course.

Remove the blind screw [1] to see which offset is set. If the mark [B] is in front, the offset is 18 mm. This setting will deliver more directional stability on fast race courses.

If the mark [B] is in the rear as illustrated, the offset is 20 mm. This setting will deliver better handling in curves.

Checking and adjusting the steering head bearing *

Check steering head bearing for play periodically. To check, put the motorcycle on a stand so that the front wheel is off the ground. Now try to move the fork forward and backward. To adjust the 5 clamping screws [1] and [3], loosen the upper triple clamp and turn the end screw [2] until no play is left. Don’t tighten the steering stem bolt all the way, otherwise the bearings will be damaged. With a plastic hammer, lightly tap on the triple clamp to release tension. Hold the middle clamp screw [3] in place with Loctite 243. Retighten the five pinch bolts.

17 Nm (pinch bolts 1)

Loctite 243 + 17 Nm (pinch bolts 3)

– If the steering head bearing is not adjusted to be free of play, the motorcycle will exhibit unsteady driving characteristics and can get out of control.

– Hold the midddle clamp screw [3] in place with Loctite 243.

If you drive with play in the steering head bearing for longer periods, the bearings and subsequently the bearing seats in the frame will be destroyed.

The steering head bearings should be regreased at least once a year

(e.g. Motorex Long Term 2000).

Check chain tension

Jack the motorcycle up on its frame so that the rear wheel no longer touches the ground.

Press the chain upward at the end of the chain sliding component. The distance between the chain and the swing arm should be approx. 8 - 10 mm

(0.31 - 0.39 in). In the course of this procedure, the upper chain portion [A] must be taut (see drawing). If necessary, correct the chain tension.

– If the chain tension is too great, parts within the secondary transmission

(chain, chain wheels and rear wheel bearings) will be subjected to unnecessary stress, resulting in premature wear and even chain breakage.

– Too much slack in the chain, on the other hand, can result in the chain jumping off the chain wheels. If this happens, the chain could also block the rear wheel or damage the engine.

– In either case the operator is likely to lose control of the motorcycle.

Correct chain tension

Loosen collar nut [1], loosen lock nuts [2], and turn right and left adjusting screws [3] equally far. Tighten lock nuts.

To ensure the correct alignment of the rear wheel, the marks at the left and right chain adjusters must be positioned identically in relation to the reference marks [B]. Tighten the counter nut of the adjusting screws.

Before tightening the collar nut, verify that the chain adjusters [4] are sitting close to the adjusting screws and that the rear wheel has been aligned with the front wheel.

Tighten collar nut [1] to 80 Nm (60 ft.lb).

– If you don’t happen to have a torque wrench at hand, make sure you have the tightening torque corrected by a KTM dealer as soon as possible. A loose axle may lead to an unstable driving behavior of your motorcycle.

– Tighten the collar nut with the required torque. A loose wheel spindle may lead to an unstable behavior of your motorcycle.

NOTE:

The large adjusting range of the chain adjusters (32mm / 1.25 in) allows you to use different secondary ratios in combination with the same chain length.

The chain adjusters [4] can be rotated by 180°.

Always mount the chain tensioner equally aligned.

Chain maintenance

For a long chain life, good maintenance is very important. Chains without

X-rings should be cleaned in fireproof solvent regularly and afterwards treated with hot grease or chain spray (e.g. Motorex Chainlube 622)..

No lubrication is allowed to reach the rear tire or the brake disk, eitherwise the road adherence and the rear wheel braking effects would be strongly reduced and the motorcycle could easily get out of control.

When mounting the chain joint, the closed side of the safety device must point in running direction.

Also check sprockets and chain guides for wear, and replace if necessary.

Chain wear

To check the chain wear, observe the following indications:

Shift the gear into idling and pull the upper chain strand with approx. 10-15 kilograms (33 lb) upwards (see figure). Now one can measure a space of 18 chain reels at the lower chain strand. The chain should be replaced at the latest when a space of 272 mm (10.70 in) is measured. Chains do not always wear off evenly, therefore repeat the measurement at different places on the chain.

NOTE:

If you mount a new chain, the sprockets should also be replaced. New chains wear faster if used on old used sprockets.

When you assemble a rear sprocket with 14t, the collar must be on the inside.

Secure the screws of the chain wheel by applying Loctite and fasten them in a crosswise order.

General information about KTM disc brakes

BRAKE CALIPERS:

The brake calipers of this series use a „floating“ mount. This means that the brake calipers are not solidly attached to the caliper support, which enables them to ”float” for maximum braking contact.Secure the screws of the caliper support with Loctite 243 and tighten to 25 Nm (19 ft.lb).

BRAKE PADS:

The brake pads are fitted with TOSHIBA TT 2701HHB sintered lining at the front and TOYO B 143 FF sintered lining at the back. These linings provide an optimal combination of dosing, brake performance and life cycle.

1

A

BRAKE DISCS:

Due to wear, the thickness of the brake disc in the area of the contact face [1] of the brake pads decreases. The brake disk must be at least

2.50 mm (front) / 3.50 mm (rear) thick at the thinnest point [A]. Check the thickness of the brake disk at several points.

– A brake disk worn down to less than 2.50 mm (Front) / 3.50 mm (Rear) is a safety risk. Have the brake disk replaced as soon as it reaches the service limit.

– Have any repairs on the brake system be performed by a KTM dealer.

BRAKE FLUID RESERVOIRS:

The brake fluid reservoirs on the front and rear wheel brakes have been designed in such a way that even if the brake pads are worn it is not necessary to top up the brake fluid. If the brake fluid level drops below the minimum level either the brake system has a leak or the brake pads are completely worn.

In this case, consult an authorized KTM dealer immediately.

BRAKE FLUID:

KTM fills the brake systems with Motorex Brake Fluid DOT 5.1 brake fluid, one of the best brake fluids is currently available. We recommend that you continue to use it. DOT 5.1 brake fluid is based on glycol ether and of an amber color. If you do not have any DOT 5.1 for refilling, you may use DOT

4 brake fluid. However, you should replace it as soon as possible with DOT

5.1.

Never use brake fluid DOT 5. The color of this silicon oil-based product is purple red. The gaskets and brake hoses of KTM motorcycles are not designed for DOT 5 brake fluid.

Have the brake fluid changed at least once annually. If you wash your motorcycle often, the brake fluid should be changed even more frequently. Brake fluid tends to absorb water. Therefore, vapor pockets may form in „old“ brake fluids even at low temperatures, causing the brake system to fail.

Adjusting the free travel at the hand brake lever

Free travel at the hand brake lever may be readjusted by using adjustment screw [1]. In this way, the position of the point of pressure (i.e. the resis-tance you feel on the hand brake lever when the brake pads are pressed against the brake disc) can be adjusted for any hand size.

When you press the hand brake lever forwards, you should have at least

3 mm free travel. Turn the adjusting screw [1] if necessary.

1

At the hand brake lever, free travel must at least be 3 mm (0.1 in). Only then may the piston in the hand brake cylinder be moved (to be recognized by the greater resistance of the hand brake lever). If this free travel is not provided, pressure will build up in the braking system, and the front-wheel brake may fail due to overheating.

Checking the brake fluid level - front brake

The brake fluid reservoir is linked with the hand brake cylinder at the handlebar and the reservoir is provided with an inspection glass. With the reservoir in a horizontal position, the brake fluid level should not drop below the middle of the glass.

If the brake fluid level drops below the minimum either the brake system has a leak or the brake pads are completely worn. In this case, consult an authorized KTM dealer immediately.

Refilling the front brake fluid reservoir *

Loosen screws [2] and remove lid [3] and membrane [4].

Place hand brake cylinder in a horizontal position and fill the brake fluid reservoir to 5 mm (0.2 in) below the rim with clean brake fluid DOT 5.1 (e.g. Motorex

Brake Fluid DOT 5.1). Replace membrane and lid, tighten screws. Rinse off spilled or overflowing brake fluid with water.

– Never use DOT5 brake fluid! It is based on silicone oil and of a purple color. Seals and brake hoses must be especially adapted to it.

– Store brake fluid out of reach of children.

– Brake fluid can cause skin irritation. Avoid contact with skin and eyes. If you get brake fluid in your eyes, rinse with plenty of water and consult a doctor

– Don’t let brake fluid get in contact with paint, it is an effective paint remover.

– Use only clean brake fluid taken from a tightly sealed container.

Checking the front brake pads

The brake pads can be inspected from below. The linings must be at least 1 mm (0.04 in) thick.

At their most worn point brake pad linings should not be thinner than 1 mm, otherwise they could lead to brake failure. For your own safety don’t put off having your brake pads changed.

If the brake pads are replaced too late so that the lining is partly or entirely worn, the steel components of the brake pad will rub against the brake disc, thereby imparing the braking effect and destroying the brake disc.

Replacing the front brake pads *

Press the brake caliper toward the brake disk, to put the brake piston in its basic position. Remove clips [1] and pull out bolt [2]. Remove brake pads from the brake caliper. Clean the brake caliper and the brake caliper support with compressed air. Check the sleeves of the guide bolts for damage, and grease guide bolts if necessary.

Mount the right brake pad and fix it with the bolt. Mount the left brake pad and insert the bolt until it stops. Mount the clips.

When mounting the brake pads, be sure to check for correct fit of the sliding metal-sheet [3] in the caliper support and of the leaf spring [4].

1

– It is very important to keep the brake disk free from oil and fatty matters.

Otherwise, the braking effect would be strongly reduced.

– After assembly, check if circlips have been fitted correctly.

– after working on the braking system, always actuate the hand brake lever or foot brake lever, respectively to ensure that the brake pads will lie against the brake disk and the pressure point is established.

Checking the rear brake fluid level

The reservoir for the rear brake disk is located on the right side of the motorcycle on the rear brake cylinder.

No air bubble should be visible in inspection glass [A] when the vehicle is parked in a vertical position.

If the brake fluid level drops below the minimum either the brake system has a leak or the brake pads are completely worn. In this case, consult an authorized KTM dealer immediately.

Refilling the rear brake fluid reservoir *

Add brake fluid as soon as a bubble is visible in inspection glass [A].

To top up, remove screw [7]. Fill DOT5.1 brake fluid (e.g. Motorex Brake Fluid

5.1) up to the mark [B] on the inside of the reservoir and remount the screw.

Spilled brake fluid must be rinsed off with water.

– Never use DOT5 brake fluid! It is based on silicone oil and of a purple color. Seals and brake hoses must be especially adapted to it.

– Store brake fluid out of reach of children.

– Brake fluid can cause skin irritation. Avoid contact with skin and eyes. If you get brake fluid in your eyes, rinse with plenty of water and consult a doctor.

– Don’t let brake fluid get in contact with paint, it is an effective paint remover.

– Use only clean brake fluid taken from a tightly sealed container.

Changing the basic position of the foot brake pedal *

The basic position of the foot brake pedal can be altered by turning the stop screw [5]. The free play at the foot brake pedal must then be adjusted by means of the piston rod [6].

Measured on the outside, the foot brake pedal must have 3-5 mm (0.12–0.20

in) of free play before the piston rod can move the piston in the brake cylinder (to be recognised from the resistance on the foot brake pedal).

If this free play is not present, then pressure can build up in the brake system when driving, causing the rear wheel to brake.The braking system overheats and may even fail completely in extreme cases.

Checking the rear brake pads

The brake pads can be inspected from the rear. The thickness of the linings may not be less than 1 mm (0.04 in).

At their most worn point brake pad linings should not be thinner than 1 mm, otherwise they could lead to brake failure. For your own safety don’t put off having your brake pads changed.

If the brake pads are replaced too late so that the lining is partly or entirely worn, the steel components of the brake pad will rub against the brake disc, thereby imparing the braking effect and destroying the brake disc.

Replacing the rear brake pads *

Press the brake caliper [1] in the direction of the chain wheel for the brake piston to reach its basic position. Remove the safety device [2], knock out the guide pin [3] from the brake caliper with a drift towards the chain wheel and remove the brake pads. Carefully clean the brake caliper with compressed air and check the sleeves of the guide pins for damage.

Slide the left brake pad into the brake caliper and fix it with the pin. Slide in the right brake pad and knock the bolt [3] in as far as it will go. Mount the safety device [2].

– It is very important to keep the brake disk free from oil and fatty matters.

Otherwise, the braking effect would be strongly reduced.

– After assembly, check if circlips have been fitted correctly.

– After working on the braking system, one must always actuate the hand brake lever or foot brake lever, respectively so as to ensure that the brake pads will lie against the brake disk and the pressure point is established.

Dismounting and mounting the rear wheel

Jack the motorcycle up on its frame so that the rear wheel no longer touches the ground.

Remove the collar nut [4], remove the chain tensioner [5] and pull out the wheel spindle [6] until you can push the rear wheel forwards.

Take the chain off the rear sprocket, pull out the wheel spindle and carefully remove the rear wheel from the swing arm.

– Do not operate the rear brake when the rear wheel has been dismounted.

– Make sure the brake disc is always on top when you lay down the wheel, otherwise the brake disc can be damaged.

– If the axle is dismounted, clean the thread of the wheel spindle and collar nut thoroughly and apply a new coat of grease to prevent the thread from jamming.

– After mounting the rear wheel, keep operating the rear brake until the pressure point returns.

– It is very important to keep the brake disk free from oil and fatty matters, otherwise the braking effects would be strongly reduced.

– Tighten the collar nut with the required torque. A loose wheel spindle may lead to an unstable behavior of your motorcycle.

Tires, air pressure

Tire type, tire condition, and air pressure level affect the way your motorcycle rides and must therefore be checked whenever you are getting ready to go anywhere on your motorcycle.

– Tire size can be found in the technical specifications and in the homologation certificate

– Tire condition has to be checked every time you want to ride your motorcycle. Before leaving, check tires for punctures and nails or other sharp objects that might have become embedded in them.

– Refer to the specific regulations in your country for minimum tire tread requirements. We recommend you replace the tires at the latest when the tread is down to 2 mm (0.08 in).

– Tire pressure should be checked regularly on a “cold” tire. Proper pressure ensures optimum driving comfort and extends the life of your tires.

27

– Do not mount tires which have not been approved by KTM. Other tires could have adverse effects on the way your motorcycle behaves.

– front and rear wheels may only be fitted with tires having the same tread layout. Use homologated tires

– For your own safety replace damaged tires immediately.

– Worn tires can have a negative effect on how your motorcycle performs, especially on wet surfaces

– If air pressure is too low, abnormal wear and overheating of the tire can result

Checking spoke tension

The correct spoke tension is very important for the stability of the wheels and thus for riding safety. A loose spoke causes the wheel to become unbalanced and before long other spokes will have come loose. Check spoke tension, especially on a new motorcycle, at regular intervals. For checking, tap on each spoke with the blade of a screwdriver (see photo). A clear tone must be the result. Dull tones are indicators of loose spokes. If necessary, have the spokes retightened and the wheel centered by a KTM dealer.

– Spokes can tear if you continue to ride with them loose. This may lead to an unstable handling of your motorcycle.

– Excessively tensioned spokes may rupture due to local overloading.The

spokes must be tensioned to 5 Nm.

Cooling system

The water pump [1] in the engine circulates the cooling liquid. The cooling liquid is cooled by the air stream. This means that the cooling effect decreases with the traveling speed. Dirty radiators additionally reduce the cooling effect.

Pressure induced by heating of the coolant in the system is controlled by a valve in the radiator cap [2]; a water temperature rising up to 120° C

(248° F) is admissible, without fear of problems.

1

1

– If possible, always check level of cooling liquid when engine is cold. If you have to open the radiator cap [2] when the engine is hot, use a rag to cover the cap and open slowly to release pressure.

Caution - scalding hazard.

– Do not detach any radiator hoses while the engine is hot. The escaping hot coolant and the steam may cause serious burns.

– In case you get burnt, hold the affected part of your body under running cold water right away.

– Coolant is toxic. Keep the coolant out of the reach of children.

– In case coolant is ingested, consult a doctor immediately.

– If coolant gets into your eyes, rinse them out with water immediately and go see a doctor.

Use a mixture of 40% antifreeze and 60% distilled water for the cooling liquid. The antifreeze should be designed for temperatures of at least -25°C. This mixture offers frost protection as well as good corrosion protection and should not be replaced by water alone.

For the cooling system, use only with high-grade antifreeze (e.g. Motorex Anti-

Freeze). Using lower-grade antifreeze agents can cause corrosion and coolant foaming.

2

10 mm when engine ist cold

Checking the coolant level

The coolant should be 10 mm (0.4 in) above the radiator fins when the engine is cold (see diagram). In the event of the coolant being drained, always fill and bleed the system.

If possible, always check the level of cooling liquid when the engine is cold.

If you have to open the radiator cap when the engine is hot, use a rag to cover the cap and open slowly to release pressure.

The cooling system must be bled after draining the cooling liquid or after adding more than 0.25 l (0.06 US gallons) cooling liquid.

Bleeding the cooling system

By removing the screw [3] at the water pump cover you can drain the coolant.

To bleed the cooling system, add coolant up to approx. 10 mm above the radiator fins when the engine is cold.

After a short ride, check the coolant level once more.

Cleaning the air filter *

The air filter must be cleaned prior to each race or whenever dust has accumulated. To clean, lift the filter box cover

(see illustration) and pull off towards the front.

Detach the bottom of the filter retaining bracket [1], tilt aside and remove the air filter [2] and filter support [3] from the filter box.

2

– Do not clean foam filter with fuel or petroleum since these damage the foam. KTM recommends the products of the company Motorex for air filter maintenance (Bio Dirt Remover and Liquid Bio Power).

- Never start your motorcycle without any air filters. otherwise, dust and dirt may penetrate and cause damage and increased wear.

- Dust and dirt can accumulate and damage the engine if the air filter is not mounted correctly.

Thoroughly wash the air filter in special cleaning fluid (Motorex Bio Dirt

Remover) and allow it to dry well. Only press out the filter, do not wring it out under any circumstances. Oil the dry air filter with a high-grade filter oil (Motorex liquid Bio Power). Also clean the air filter box. Check the carburetor collar for damage and that it is filled correctly.

Place the air filter on the filter support and insert both in the center of the filter box. Hold in place with the filter retaining clip.

Exhaust system *

If the end cap [4] can be removed, the silencer is filled with glass-fiber yarn.

Have the filling checked regularly by an authorized KTM workshop (see

Lubrication and Service Chart). The insulating material fibers escape through the holes in the perforated pipe with time, causing the silencer to “burn out”.

In addition to causing a higher noise-level, it will also affect the power characteristic. The insulating material suitable for your exhaust is available from your authorized KTM workshop.

To replace the glass-fiber yarn set [5] remove the end cap and pull off the outer pipe [6]. Tape a new glass-fiber yarn set to the inner tube and slide on the outer pipe. Mount the end cap.

Make sure the caps are screwed on tightly. Mount the muffler stress-free before tightening the fixing screws.

The exhaust system becomes very hot while the motorcycle is running. Do not start work on the exhaust system until it has properly cooled down, to avoid burns.

Changing the original position of the clutch lever

The adjusting screw [1] can be used for individual adjustment of the original position of the clutch lever, thus allowing adjustment to an optimal position for every hand size.

The clutch lever moves closer to the handlebar if the adjusting screw is turned in a counterclockwise direction. The clutch lever moves away from the handlebar if the adjusting screw is turned in a clockwise direction.

Adjustment of the clutch lever position is only possible within certain limits.

Only turn the adjusting screw manually and never apply excessive force.

Checking the oil level of the hydraulic clutch125 SX

To check the oil level in the master cylinder of the clutch remove the cover.

For this purpose, remove screws [2] and cover [3] together with the rubber boot [4]. The oil level in the horizontal-standing master cylinder should be

4 mm below the upper edge.

If necessary, add SAE 10 biodegradable hydraulic oil (Motorex clutch fluid

75), available from your authorized KTM shop.

KTM uses biodegradable, hydraulic mineral oil to actuate the hydraulic clutch in 125/200 models. Do not mix this oil with any other hydraulic oil. Always use original KTM hydraulic oil (available from your authorized KTM workshop) to make sure your clutch operates smoothly. Never refill with brake fluid.

Checking the oil level of the hydraulic clutch 250 SX

To check the oil level in the master cylinder of the clutch remove the cover.

For this purpose, remove screws [5] and cover [6] together with the rubber boot [7]. The oil level in the horizontal-standing master cylinder should be

4 mm below the upper edge.

If necessary, add DOT 5.1 brake fluid (Motorex Brake Fluid 5.1).

BREMBO clutch fittings are installed in the 250/300 models and filled with

DOT 5.1 brake fluid. To make sure the clutch operates smoothly, never add hydraulic oil to these systems.

Bleeding the hydraulic clutch *

The clutch control needs to be bled as soon as the resistance in the clutch lever starts to feel unresponsive. You will need to use a bleeding syringe (special tool). Please note that Motorex 75 clutch fluid must be used for the 125 models and Motorex DOT. 5.1 brake fluid for the 250 models.

Both are available from your KTM dealer.

Turn the handlebar until the master cylinder is in a horizontal position, remove the screws [2], the cover [3] and the rubber boot [4].

Carburetor adjustment *

Basic information on the original carburetor setting

The original carburetor setting was adapted for an altitude of approx. 500 meters (1600 ft.) above sea level, and the ambient temperature of approx. 20° C (68° F), mainly for off-road use and central European premium-grade fuel (95 ROZ).

Mixing ratio (2-stroke motor oil/super fuel): 1:40 (125 SX), 1:60 (250 SX)

Basic information on changing the carburetor setting

Always start with the original carburetor setting (the provided factory setting is meant for break-in operation; after the break-in period, the carburetor needs to be adjusted according to the carburetor datasheet - see appendix). Essential requirements are a clean air filter system, air-tight exhaust system and an intact carburetor. Experience has shown that adjusting the main jet, the idling jet and the jet needle is sufficient and that changes of other parts of the carburetor will not greatly affect engine performance.

RULE OF THUMB: high altitude or high temperatures > choose leaner carburetor adjustment low altitude or low temperatures > choose richer carburetor adjustment 31

– Only use premium-grade gasoline ROZ 95 (USA = Premium PON 91) mixed with high-grade two-stroke engine oil. Other types of gasoline can cause engine failure, and will void your warranty.

– Only use high-grade 2-stroke engine oil of known brands (e. g. Motorex Cross Power 2T).

– Not enough oil or low-grade oil can cause erosion of the piston. if you use too much oil the engine can start smoking and foul the spark plug and the exhaust control system.

– In the case of a leaner adjustment of the carburetor, proceed cautiously. Always reduce the jet size in steps of one number to avoid overheating and piston seizure.

NOTE: If the engine does not run properly despite a changed adjustment, look for mechanical faults and check the ignition system.

General information on carburetor wear

Engine vibrations subject the throttle slide, jet needle, float needle valve and the needle jet to extreme wear. Wear leads to malfunctioning of the carburetor (e.g. over-enrichment). These parts should be replaced after 100 operating hours. The carburetor body, main jet holder and the float support should be replaced after 200 operating hours.

Idling range A

Operation with closed throttle valve. This range is influenced by the position of the air control screw [1] and the air control screw [2]. Only make adjustments when the engine is hot.

To this end, slightly increase the idling speed of the engine by means of the air control screw. Turning it clockwise produces a higher idling speed and turning the screw counterclockwise produces a lower idling speed. Create a round and stable engine speed using the air control screw (basic position of the air control screw = open by 1.5 turns). Then adjust to the normal idling speed by means of the air control screw.

Opening up B

Engine behavior when the throttle opens. The idle jet and the shape of the throttle valve influences this range. If, despite good idling-speed and partthrottle setting, the engine sputters and smokes when the throttle is fully opened and develops its full power not smoothly but suddenly at high engine speeds, the mixture to the carburetor will be too rich, the fuel level too high or the float needle is leaking.

Part-throttle range C

Operation with partly open throttle valve. This range is only influenced by the jet needle (shape and position). The optimum part-throttle setting is controlled by the idling setting in the lower range and by the main jet in the upper range.

If the engine runs on a four-stroke cycle or with reduced power when it is accelerated with the throttle partly open, the jet needle must be lowered by one notch. If then the engine pings, especially when accelerating under full power at maximum engine revs, the jet needle should be raised.

If these faults should occur at the lower end of the part throttle range at a four-stroke running, make the idling range leaner; if the engine pings, adjust the idling range richer.

Draining the float chamber of the carburetor

Following every wet-cleaning procedure, the float chamber of the carburetor should be drained in order to remove any water that may have penetrated into it. Water in the float chamber leads to engine malfunction.

Make sure you do this while the engine is cold. Close the fuel tap, and place a cloth under the carburetor, which is capable of absorbing the leaking fuel. Unscrew the plug [1] and clean it with compressed air. Then, mount the plug together with the gasket, open the fuel tap, and check the float chamber for leaks.

1

Fuel is easily flammable and toxic. When handling fuel, be sure to exercise the utmost caution. Never perform any work on the fuel system near open flames or burning cigarettes. Always allow the engine to cool off first.

Immediately clean up any fuel which may have been spilled. Materials saturated with fuel are also easily flammable. In case you ingested fuel or fuel splashed into your eyes, consult a doctor immediately.

Dispose of the fuel properly.

Checking the float level *

Arrange the carburetor diagonally at about 60° so that the spring in the float needle valve is not pressed together. In this position, the edge of the float should be parallel with the float chamber sealing surface (see illustration).

CLEANING

»

Clean your motorcycle regularly in order to maintain the beauty of its plastic surfaces.

The best manner would be to use warm water that has been mixed with a normal brand-name washing detergent and a sponge.

The hard dirt can be removed before washing with the help of a soft water jet.

If using a power washer, do not point the water jet at the electric components, plugs, cables, bearings, carburetor, etc. The high pressure will cause water to penetrate into the components and can cause them to malfunction or lead to premature wear.

– Before cleaning with water, plug the exhaust pipe to prevent water ingress.

– You should use normal brand-name detergents to clean the motorcycle. Especially dirty parts should also be cleaned with the help of a paint brush.

– After the motorcycle has been rinsed with a soft water jet, it should be dried by air pressure and a cloth. Then take a short drive until the engine has reached the working temperature and also use the brakes. By warming these components, the residual water can evaporate from inaccessable parts of the engine and the brakes.

– Slide back the protective covers on the handlebar-mounted instruments so that any water that may have seeped into this part of the motorcycle is allowed to evaporate.

– After the motorcycle has cooled down, oil and grease all the gliding bearing parts. Treat the chain with a chain spray.

– To prevent failures in the electric system, you should treat the ignition lock, the emergency OFF switch, the short circuit button, the light switch and the socket connectors with contact spray.

CONSERVATION FOR WINTER OPERATION

»

In the event that the motorcycle is also used in winter and on roads where one has to expect salt spraying, you will have to take precautions against the aggressive road salt.

– clean the motorcycle thoroughly and let it dry after each ride

– treat the engine, carburetor, swing arm, and all other bare or galvanized parts (except for brake discs) with a wax-based anti-corrosion agent.

35

Keep the anti-corrosion agent from getting into contact with the brake discs, otherwise this will significantly reduce the braking power.

After rides on salted roads, clean motorcycle thoroughly with cold water and let it dry well.

STORAGE

»

Should you wish to make a pause over a longer space of time, please observe the following instructions:

– Clean motorcycle thoroughly (see chapter: CLEANING)

– Change engine oil (old engine oil contains aggressive contaminants).

– Check antifreeze and amount of cooling liquid.

– Let the engine warm up again, close fuel cock and wait until the engine dies off by itself. In this way the carburetor jets are prevented from becoming resin- clogged by the old fuel.

– Remove spark plug and fill in approx. 5 ccm of engine oil into the cylinder through the opening. Actuate kick-starter 10 times in order to distribute the oil onto the cylinder walls and mount the spark plug.

– Let fuel flow out of tank into an appropriate container.

– Correct tire pressure.

– Lubricate bearing points of the control levers, footrests, etc. as well as the chain.

– The storage place should be dry and not be subjected to too big temperature fluctuations.

– Cover the motorcycle with an air permeated tarp or blanket. Do not use non airtight materials as a possible humidity might not be able to escape and thereby cause corrosion.

It would be very bad to let the engine run for a short time during the storage period. The engine would not get warmed up enough and the thus developed steam would condense during the combustion process and cause the valves and exhaust to rust.

USE AFTER A PERIOD OF STORAGE

– Fill up the tank with fresh fuel.

– Check the motorcycle as before each start (see driving instructions)

– Take a short, careful test ride first.

NOTE: Before you put your motorcycle away for the winter, you should check all parts for their function and wear. Should any service jobs, repairs, or any refitting be necessary, you should have them carried out during the off-season (lower workload at mechanics' shops).

This way, you can avoid the long waiting times at your shop at the beginning of the next biking season.
