LIST OF SECTIONS
Introduction
This manual contains information on how to perform
the usual vehicle service procedures. This manual
does not describe all of the procedures necessary to
repair and service the vehicle in detail.
This publication is intended for use by aprilia dealers
and their trained, experienced mechanics.
The descriptions of many service and repair operations have been intentionally omitted, as it is assumed
that the users of this manual have basic mechanical
training and basic knowledge of the procedures used
for motor vehicle repair, as well as safety rules necessary to ensure their safety and that of the public while
repairing motor vehicles.
Therefore, it is imperative that you do not attempt to
perform any maintenance or repair procedure with
which you are not throughly familiar, and fully qualified
to perform. Such an attempt can result in defective
repairs, which can be dangerous both to you, to the
owner or user of the vehicle, and to the public in
general.
The information and illustrations in this manual are
current as of the manual’s date of issue.
Since aprilia s.p.a. continually improves its products,
there may be some differences between the vehicle
you are servicing and the illustrations and instructions
given in this manual. If you have any questions
regarding the applicability of any service procedure
given in this manual, contact aprilia consumer services (A.C.S.). A.C.S. Technical Counselors, will be
able to assist you with any problems you might face
as well as providing you with information on any
updates and technical changes to the vehicle you are
servicing.

vehicle servicing procedures will be documented and
distributed to aprilia dealers all over the world. These
changes will be incorporated in later editions of this
manual.
aprilia s.p.a. reserves the right to modify specifications and characteristics of any of its models at any

SAFETY WARNINGS
The following precautionary warnings are used throughout this manual in order to convey the following messages:
Safety warning. When you find this symbol on the vehicle or in the manual, be careful to the potential
risk of personal injury. Non-compliance with the indications given in the messages preceded by this
symbol may result in grave risks for your and other people’s safety and for the vehicle!
WARNING
Indicates a potential hazard which may result in serious injury or even death.
CAUTION
Indicates a potential hazard which may result in personal injury or damage to the vehicle or other property.
NOTE The word “NOTE” in this manual precedes important information or instructions.
PRECAUTIONS AND GENERAL INFORMATION
Keep strictly to the following instructions when repairing, disassembling or reassembling the motorcycle.
WARNING
Never use a naked flame for any operation whatsoever.
Before starting any servicing or inspection job on the motorcycle, stop the engine, remove the key, wait
until the engine and exhaust have cooled down and, if possible, raise up the motorcycle, using the correct
equipment standing on a solid, level floor. Be especially careful about the parts of the engine and exhaust
that are still hot, to avoid burns.
Motorcycle parts are not edible; do not bite, suck, chew or swallow any of the motorcycle parts for any
reason whatsoever.
Unless expressly stated otherwise, follow the disassembly steps in reverse order when reassembling
units.
The overlapping of operations in references to other chapters must be interpreted in a logical way, to avoid
the unnecessary removal of components.
Never use the fuel as a solvent to clean the motorcycle.
Disconnect the battery negative lead (-) control unit and spark plug, if electric welding has to be performed.
Always be careful about the safety of the others when two or more people are working at the same time.
BEFORE DISASSEMBLY
Remove all dirt, mud, dust and foreign bodies from the motorcycle before removing any components.
When specified, use the service tools specially designed for this motorcycle.
DISASSEMBLY OF COMPONENTS
Never loosen and/or tighten nuts and bolts with pliers or other similar tools; always use a proper wrench.
Mark the positions of all unions and connections (hoses, wires, etc.) before disconnecting them with clearly distinguishable marks.
Each component must be clearly marked so that it can be identified for refitting.
Clean and wash each removed component with fire-proof solvent.
Paired components must be kept together, as they become “matched” after normal wear. Some paired components
must either be used together or both replaced.

REFITTING COMPONENTS
CAUTION
Never use a circlip twice. When a circlip is removed, it must be replaced with a new one.
When assembling a new circlip, be careful not to stretch its ends more than strictly necessary to place it
on the shaft.
After installing a circlip, make sure that it is completely and firmly inserted in its seat.
Do not use compressed air to clean bearings.
NOTE Bearings must turn freely with no sticking and/or noise. Replace bearings that show any roughness when
the inner race is turned.
Use only Original aprilia Spare Parts for replacement.
Use only the recommended lubricants and sealing agents.
Lubricate all metal parts (where possible) before refitting them.
When tightening nuts and bolts, start with the larger diameter or inner ones and proceed in diagonal order.
Tighten them in gradual steps before applying the final tightening torque.
Always replace all self-locking nuts, gaskets, circlips, snap rings, O-rings, split pins and screws, if there is any sign
of thread damage.
Thoroughly clean all mating surfaces, oil seal rims and gaskets before reassembly.
Apply a thin film of lithium-based grease to oil seal rims.
Refit the oil seal and bearings with the identification mark or serial number facing outwards (visible).
Lubricate bearings thoroughly when fitting.
Check to make sure that each component has been fitted properly.
After carrying out repairs or routine servicing, go through the pre-ride checklist thoroughly before riding the motorcycle or allowing it to be ridden. Take a trial run in a parking lot or other low traffic area before returning the motorcycle to its owner.
USING THE MANUAL
HOW TO CONSULT THE MANUAL

SAFETY WARNINGS FOR FUEL, LUBRICANTS COOLANT AND OTHER COMPONENTS
FUEL
WARNING
The fuel used for the propulsion of combustion engines is extremely inflammable and can become explosive under certain conditions.
Refueling and servicing operations should be carried out in well-ventilated areas with the engine switched
off.
Do not smoke when refueling or in the vicinity of fuel vapors. All contact with naked flames, sparks or any
other possible source of ignition or explosion must be absolutely avoided.
Do not allow fuel to spill out when filling the tank, as it could ignite on contact with the hot surfaces of the
engine.
If fuel is accidentally spilt, check that the zone is perfectly dry before starting the motorcycle.
Fuel expands with heat and under direct sunlight.
For this reason, never fill the fuel tank right up to the brim.
Close the filler cap properly after refueling.
Do not allow fuel to come into contact with the skin. Do not swallow fuel or inhale the vapors. Do not
transfer fuel from one container to another with a tube.
DO NOT DISPOSE OF FUELIN DRAINS, WATER COURSES OR THE SOIL.
KEEP OUT OF REACH OF CHILDREN.
Use only leaded (4-star ) or unleaded petrol with minimum octane rating 95 (N.O.R.M.) and 85 (N.O.M.M.)
ENGINE OIL
WARNING
Engine oil can cause serious skin damage if handled on a daily basis over a long period of time.
You are advised to wash your hands thoroughly after handling the oil.
Do not dispose of the oil in drains, watercourses or the soil.
Take the oil to (or have it collected by) the nearest used oil disposal agency or the supplier.
You are advised to wear rubber gloves when carrying out maintenance work.
Check the engine oil after the first 625 miles (1000 km) and then every 1,875 miles (3000 km). Change the engine
oil every 3,750 mi (6000 km), see CHANGING THE ENGINE OIL AND THE ENGINE OIL FILTER.

TRANSMISSION OIL
WARNING
Transmission oil can cause serious skin damage if handled on a daily basis over a long period of time.
You are advised to wash your hands thoroughly after handling the oil.
Do not dispose of the oil in drains, watercourses or the soil.
Take the oil to (or have it collected by) the nearest used oil disposal agency or the supplier.
You are advised to wear rubber gloves when carrying out maintenance work.
Change the transmission oil after the first 625 miles (1000 Km) and then every 15,000 miles (24000 km) (see
engine workshop manual).
BRAKE FLUID
WARNING
Brake fluid can cause irritation if it comes into contact with the skin or eyes.
Thoroughly wash any parts of the body that come into contact with the fluid and contact an eye specialist
or doctor if the fluid comes into contact with the eyes.
DO NOT DISPOSE OF THE FLUID IN DRAINS, WATER COURSES OR THE SOIL.
KEEP OUT OF REACH OF CHILDREN.
Avoid splashing brake fluid on the plastic or painted parts of the motorcycle, as it will cause damage.
Check the brake fluid level every 3,750 miles (6000 km), (CHECKING AND TOPPING UP THE FRONT BRAKE
FLUID); change the fluid every two years, (CHANGING THE FRONT BRAKE FLUID).
CAUTION
Do not use fluids other than those specified and do not top up with different fluids, as this will damage the
braking system.
Do not use fluids that have been stored in old containers or that have been open for a long time.
Sudden variations in the play or looseness of the brake levers are caused by problems in the hydraulic
circuits.
Check very carefully to ensure that there is no oil or grease on the brake discs and friction gaskets, especially after servicing or inspections.
Check that the brake hoses are not twisted or worn.
Make sure no water or dust gets into the circuit accidentally.
You are advised to wear rubber gloves when working on the hydraulic circuit.
FORK OIL
WARNING
Fork oilcan cause serious skin damage if handled on a daily basis over a long period of time.
You are advised to wash your hands thoroughly after handling the oil.
Do not dispose of the oil in drains, water courses or the soil.
Take the oil to (or have it collected by) the nearest used oil disposal agency or the supplier.
You are advised to wear rubber gloves when carrying out maintenance work.
Altering the setting of the dampers and/or the viscosity of the oil in them could partially change the responsiveness of the suspension.
The viscosity grades can be chosen on the basis of the kind of ride wanted for the motorcycle.

COOLANT
WARNING
Coolant is harmful if swallowed; it may cause irritation if it comes into contact with the eyes or skin.
Rinse for a long time with water and call a doctor if coolant comes into contact with the skin or eyes.
If swallowed, induce vomiting, rinse the mouth and throat with lots of water and call a doctor immediately.
DO NOT DISPOSE OF THE FLUID IN DRAINS, WATER COURSES OR THE SOIL.
KEEP OUT OF REACH OF CHILDREN.
WARNING
Be careful not to spill coolant on the hot parts of the engine; it may catch fire and burn with invisible
flames.
You are advised to wear rubber gloves when carrying out maintenance work.
Do not use the motorcycle if the coolant is below the minimum level.
Check the coolant level before starting and every 1,250 miles (2000 km), (CHECKING AND TOPPING UP THE
COOLANT); change the coolant every two years, (CHANGING THE COOLANT).
The coolant solution is made up of 50% water and 50% antifreeze. This is the ideal mixture for most running
temperatures and ensures good protection against corrosion.
You are advised to keep the same mixture in the warmer season as well, to reduce loss by evaporation and avoid
frequent topping-up.
This will also reduce the quantity of mineral salt deposits left in the radiator when the water evaporates and ensure
that the cooling system keeps working at the same level of efficiency.
If the external temperature falls to below zero degrees centigrade, check the coolant circuit frequently, adding a
higher concentration of antifreeze if necessary (up to a maximum of 60%).
Use only distilled water in the solution, to avoid damaging the engine.
NOTE Different antifreeze fluids have different characteristics. The guaranteed grade of protection is given on the
label on the product container.
CAUTION
Use only antifreeze and anti-corrosion fluids without nitrite, as these guarantee protection to -35°C (-31°F).

CARBON MONOXIDE
If a servicing operation has to be carried out with the engine running, make sure this is done in the open air or in a
well-ventilated area.
Never run the engine in enclosed spaces.
If you have to work in an enclosed space, use an exhaust fume extraction system.
WARNING
Exhaust fumes contain carbon monoxide, a poisonous gas that can cause loss of consciousness and
death.
Run the engine in the open air or, if you have to work in an enclosed space, use an exhaust fume extraction system.
COMPONENTS AT HIGH TEMPERATURES
WARNING
The engine and the exhaust system components get very hot and stay hot for a certain time after the
engine has been switched off.
Wear heat-proof gloves if you have to handle these components, or else wait until the engine and exhaust
system have cooled down.
RUNNING-IN RULES
WARNING
After the motorcycle has been operated for 625 miles (1000 km), perform the checking operation shown in
the column “After running-in” of the REGULAR SERVICE INTERVALS CHART.
The internal parts of the engine and transmission must be properly run-in to ensure their long life and dependable
operation. If possible, while breaking in your motorcycle, ride on hilly roads and/or roads with many curves so that
the engine and transmission undergo lots of speed changes.
NOTE The best vehicle speeds and acceleration will only be obtained after the first 625 miles (1000 km) of running-in.
Follow these instructions carefully:
• Do not turn the accelerator handlebar fully at low speeds, either during or after running-in.
• 0-62 mi (0-100 km)
During the first 62 miles (100 km) use the brakes with care, avoiding any sudden or prolonged braking actions.
This will allow the correct bedding of friction material from the pads on the brake disc.
• 0-312 mi (0-500 km)
For the first 312 miles (500 km), do not ride the vehicle at more than 80% of its foreseen maximum speed.
• Avoid keeping a constant speed on long sections of road.
• After the first 625 miles (1000 km), progressively increase speed until you reach maximum performance levels.

PRECAUTIONS AND GENERAL INFORMATION
Keep strictly to the following instructions when repairing, disassembling or reassembling the motorcycle.
1
WARNING
Never use a naked flame for any operation whatsoever.
Before starting any servicing or inspection job on the motorcycle, stop the engine, remove the key, wait
until the engine and exhaust have cooled down and, if possible, raise up the motorcycle, using the correct
equipment standing on a solid, level floor. Be especially careful about the parts of the engine and exhaust
that are still hot, to avoid burns.
Motorcycle parts are not edible; do not bite, suck, chew or swallow any of the motorcycle parts for any
reason whatsoever.
Unless expressly stated otherwise, follow the disassembly steps in reverse order when reassembling
units.
Do not run the engine in closed or badly ventilated rooms.
Handle gasoline, which is extremely flammable and highly explosive, with the utmost care.
Never use the fuel as a solvent to clean the motorcycle.
Always be careful about the safety of the others when two or more people are working at the same time.
– Only use genuine aprilia SPARE PARTS.
– Only use the recommended lubricants.
– Use, when necessary, the special tools designed for this vehicle.
– When tightening screws, nuts and bolts, start with the largest diameter or innermost fasteners, and tighten diagonally across their layout.
– Carefully clean all disassembled parts with a nonflammable detergent.
– Lubricate the parts (naturally, where possible) before refitting.
– Make sure that all parts have been refitted correctly.
– Always replace gaskets, grommets, circlips, O-rings and split pins with new ones.
– Mark the positions of all connection joints (pipes, cables, etc.) before disconnecting them, using a different
distinguishing mark.
Each piece must be clearly marked for easy identification during installation.
CAUTION
Never use a circlip twice.
When a circlip is removed from a shaft, it must be replaced with a new one.
When fitting a new circlip, take care not to stretch its ends any more than is strictly necessary to fit it to the
shaft.
After installing a circlip, make sure that it is completely and firmly inserted in its seat.
SPARE PARTS
Only use original aprilia Spare Parts. Original aprilia Spare Parts are high quality and have been designed and
built especially for aprilia vehicles.
CAUTION
The use of anything other than genuine aprilia spare parts may cause performance problems and damage
to the vehicle.

Battery electrolyte is toxic, caustic and may burn
in contact with the skin, since it contains sulfuric
acid. Wear protective clothing, a face mask and/or
safety goggles when performing maintenance.
If any electrolyte fluid comes into contact with the
skin, rinse thoroughly with cool running water.
Should it accidentally contact your eyes, flush
immediately with running water for fifteen minutes, then immediately seek professional medical
attention.
Should you accidentally swallow battery electrolyte, drink large amounts of milk or water, then
continue with milk of magnesia or vegetable oil.
See a physician immediately.
Since the battery gives off explosive hydrogen
gas, keep away from open flames, sparks or
cigarettes, or any other source of heat.
Make sure the area is adequately ventilated during
recharging or while running the engine; avoid
inhaling the fumes emitted while recharging the
battery.
KEEP OUT OF REACH OF CHILDREN.
Be careful not to tilt the vehicle too far, to avoid
hazardous battery fluid leaks.
CAUTION
Never reverse the battery cable connections.
Connect and disconnect the battery with the
ignition switch set to “ ” to avoid damaging
certain components.
Connect first the positive cable (+), then the
negative (–).
Disconnect in reverse order.
The battery fluid is corrosive.
Do not spill or spatter it, especially on plastic
parts.
If you are installing a “MAINTENANCE-FREE”
battery, recharge using a specifically designed
battery charger (with constant voltage/amperage
or constant voltage).
Using a conventional battery charger could damage the battery.

WARNING
The brakes are the parts that guarantee the most
safety and therefore, they must always be kept in
perfect working order.
Always check the brakes before using the vehicle.
A dirty disc will soil pads, which will lead to a
reduction in braking efficiency. Dirty pads must be
replaced, while a dirty disc must be cleaned using
a high-quality degreaser.

Brake fluid must be replaced every two years.
NOTE This vehicle is fitted with front and rear disc
brakes, with separate hydraulic systems.
The following information refers to a single brake
system but is valid for both systems.
As the pads wear out, the brake fluid level in the tank
falls to automatically compensates for their wear.
The brake fluid tanks are located beneath the handlebar cover, close to the brake lever couplings.
Check the level of brake fluid in the tanks on a regular
basis, see (CHECKING) as well as the wear of the
pads, see (CHECKING WEAR OF THE BRAKE
PADS).
WARNING
Do not use the vehicle if any liquid is leaking from
the brake system.
CHECKING
To check the level:
NOTE Place the vehicle on a firm, flat surface.
•
•
•
Place the vehicle on the center stand.
Turn the handlebar so that the fluid in the brake
fluid tank is parallel to the “MIN” mark on the glass
gauge (1).
Check that the fluid in the tank is over the “MIN”
mark on the glass gauge (1).
MIN = minimum level.
If the fluid does not reach the “MIN” mark:

CAUTION
As the pads wear out, the brake fluid level falls
progressively.
•
Check the wear of the brake pads, (CHECKING

CAUTION
Topping up to the “MAX” level must only be
carried out when new pads have been fitted.
As the pads wear out, the brake fluid level falls progressively.
Do not fill the tank to “MAX” with worn pads. This
will cause the fluid to overflow from the tank when
the pads are replaced.
Fill the tank (3) with brake fluid, LUBRICANT CHART,
until the glass gauge (1) is completely covered.
To refit the parts, follow this procedure in reverse.
CHECKING WEAR OF THE BRAKE PADS
Carefully read DISC BRAKES.
The following information refers to a single brake
system but is valid for both systems.
Check the wear of the brake pads after the first 625 mi
(1,000 km), and every 1,250 mi (2,000 km) thereafter.
The wear of the disc brake pads depends on use, riding
style and road conditions.
Wear is increased during use on dirty or wet roads.
WARNING
It is especially important to check the wear of the
brake pads before every trip.
To quickly check the wear on the pads:
• Place the vehicle on the center stand.
• Visually inspect the brake disc and pads, as follows:
FRONT BRAKE CALIPERS
– Check from the front, looking upwards, for both
calipers.
REAR BRAKE CALIPER
– Check from the rear, looking upwards, for both pads (C).
3
WARNING
Excessive wear on the pad friction material would
cause the metal pad support to come into direct
contact with the disc, creating a metallic grinding
noise and producing sparks from the clamp; the
braking effectiveness, safety and integrity of the
disc would thus be compromised.
• If the thickness of the friction material (even of a
single pad) is reduced to approximately 0.059 in (1.5
mm), replace both pads.
– Front pads (2).
– Rear pads (3).

BLEEDING THE BRAKING SYSTEM
(FRONT ONLY)
Carefully read DISC BRAKES.
If air is present in the hydraulic system, it acts as a bearing and absorbs the majority of the pressure exercised
by the brake pump, reducing the effectiveness of caliper action during braking.
You can tell if there is air in the system from the

BLEEDING THE INTEGRAL BRAKING SYSTEM
Carefully read DISC BRAKES.
If air is present in the hydraulic system, it acts as a bearing and absorbs the majority of the pressure exercised
by the brake pump, reducing the effectiveness of caliper action during braking.
You can tell if there is air in the system from the “sponginess” of the brake control and reduced braking efficiency.
WARNING
Since these conditions would be extremely dangerous for the vehicle and the rider, it is absolutely necessary to bleed the hydraulic circuit
after the brakes have been refitted and normal
conditions of brake system use have been restored.
NOTE The left-hand pump lever acts on the rear

WHEELS AND TIRES
Carefully read PRECAUTIONS AND GENERAL
INFORMATION.
CHECKING THE WHEELS
Make sure that the wheel rims are neither cracked nor
deformed. Replace if necessary.
Check the wheel eccentricity.
If it is deformed beyond tolerance limits, check the rim
and the bearings.
Replace the wheel if necessary.
Eccentricity limits:
Vertical: 0.078 in (2 mm)
Lateral: 0.078 in (2 mm)
Check the wheel balancing.
Rotate the wheel slowly several times and observe
the position in which it stops.
If the wheel is not statically balanced, it will always
stop in the same place. Place a balancing weight on
the lightest point of the wheel (top).
TIRES
This vehicle is equipped with tubeless tires (no inner
tube).
WARNING
Periodically check the inflation pressure of the
tires at ambient temperature, see (TECHNICAL
SPECIFICATIONS).
If the tires are warm, the measurement will not be
correct.
Always measure before and after any long trips.
If the inflation pressure is too high, the shocks of
rough terrain are not absorbed and are transmitted to the handlebars, making for an uncomfortable ride and also diminishing the vehicle’s ability
to adhere to curves.

chap. 2
Routine maintenance operations

If the tire is underinflated (pressure is too low), the
sidewalls (1) are under greater stress and the tire
itself may slip or detach from the rim with consequent loss of control.
The tires may slip off the rims if the rider brakes
suddenly, and the vehicle may skid on curves.
1
Check the surface state and wear, since tires in
poor condition do not adhere properly to the road
and adversely affect vehicle handling.
2
Some types of tires, approved for use on this
vehicle, come equipped with wear indicators.
Various kinds of wear indicators are available.
Ask your local dealer for instructions on how to
check for wear.
Visually inspect the tire condition and have them
replaced if they are worn.
If the tires are old, even if they are not completely
worn out, they may harden and be unable to
ensure good adherence.
In this case have the tires replaced.
Have the tire replaced if worn or if the tread area
contains any puncture larger than 0.196 in (5 mm)
across.
After repairing a tire, have the wheels balanced.
Use only tires of the size indicated by the manufacturer, see (TECHNICAL SPECIFICATIONS).
Never install tires with inner tubes on rims for
tubeless tires, and vice-versa.
Make sure the inflation valves are always capped,
to prevent the tires from deflating suddenly.
Changing, repairing, maintaining and balancing
the tires are all very important tasks; they must
therefore be carried out using the appropriate
tools and expertise.
We therefore recommend that you contact your
nearest aprilia dealer or tire specialist to perform
the aforementioned operations.
If the tires are new, they may be covered with a
slippery coating: drive carefully for the first few
miles. Do not grease the tires with inappropriate
substances.

FUEL PUMP AND TANK
EMS FUEL INJECTION SYSTEM
This fuel injection system has integrated injection and ignition.
Injection is indirect into the manifold, using an electronic fuel injector.
Injection and ignition are phased to a 4-stroke cycle, using a phonic wheel dropped on the camshaft control and a
reluctance variation sensor.
Carburation and ignition are both controlled according to engine revs and gas valve opening.
Further corrections are made according to the following parameters:
- Coolant temperature
- Intake air temperature
- Ambient pressure
The system corrects the idling supply with a cold engine using a stepper motor, which is inserted into a by-pass
circuit of the gas valve. The control unit controls the stepper motor and the fuel injector opening time, thus guaranteeing idling stability and correct carburation.
Carburation is controlled in all operating conditions by modifying the opening time of the fuel injector.
Fuel supply pressure is kept constant according to ambient pressure.
The supply circuit is comprised of:
- Fuel pump
- Fuel filter
- Fuel Injector
- Pressure regulator
The pump, filter and regulator are inserted into the fuel tank on a single support.
The fuel injector is connected by two pipes with snap-on couplings. This forms a continual circuit that prevents the
risk of fuel boiling. The pressure regulator is located at the end of the circuit.
The fuel pump is controlled by the EMS control unit; this guarantees vehicle safety.
The ignition circuit is comprised of:
- High tension coil
- High tension cable
- Shielded cap
- EMS control unit
- Spark plug
The EMS control unit controls the ignition with optimum spark lead and at the same time, guarantees the timing of
the 4-stroke cycle (ignition only during the compression stage).
The EMS fuel injection-ignition system controls engine operations by means of a pre-set program.
In the event that any input signals are lacking, acceptable engine operation is in any case guaranteed in order to
allow the user to reach the repairs workshop.
Of course, this is not possible when the stroke-revs signal is lacking or when a malfunction occurs within the control
circuits:
- Fuel pump
- High tension coil
- Fuel injector

SYSTEM DESCRIPTION
The cooling system is comprised of a centrifugal pump that is coaxial to the countershaft and for this reason, it
makes the same number of revolutions as the engine shaft.
The pump has two intake pipes and one outlet pipe.
The outlet feeds the cylinder and as a result, the head; one intake comes from the head and is controlled at the
pump intake by the thermostat cap.
The main seal of the thermostat operates on the main intake pipe of the pump, which comes from the radiator.
The radiator is supplied by the head outlet; the expansion tank is parallel to the radiator with pipes on two levels:
delivery on top (in air) and fluid return at the bottom (in the fluid).
The system is of the two-way type.
The first path is formed by circulation inside the engine and involves the pump, cylinder and head; this type of
circulation is completely enabled when the thermostat is fully closed.
The second path is enabled when the thermostat is fully open and is the main circulation, involving pump, cylinder,
head, radiator, and expansion tank. For medium thermostat openings, both circuits are partially enabled and
therefore, the two paths overlap.
This type of circuit is defined as having an intake thermostat. The thermostat is crossed by an inverse flow; that is,
with cold water, which tends to lower the temperature of the wax cell.
This system allows optimization of the heating stages of the engine.
The expansion tank, which is parallel to the radiator and inserted into the main circuit, guarantees autobleeding
during operation.
For the system filling stages, there is a bleeder at the head outlet (see filling regulations).
The electric cooling fan is controlled by the fuel injection system and the relevant temperature is measured on the
engine head.

CHECKING THE PARTS
Rod
The sliding surface must not be lined and/or scratched.
If the lines are deep, replace the rod.
Use a dial gauge to check that any curving in the rod is
less than the limit value.
If above the limit value, replace the rod.
Curve limit: 0.007 in (0.2 mm).
WARNING
NEVER straighten a curved rod; this will weaken
the structure of the vehicle, making it dangerous to
use.
Wheel support
Make sure there is no damage and/or cracking and
replace if necessary.
Spring
Make sure that the spring is in perfect working order.
Pumping element
Make sure it is in perfect working order and replace if
there are any signs of damage.
ADJUSTING THE REAR SUSPENSION
The rear suspension is comprised of a pair of dualeffect shock absorbers (braking in compression/
extension), fixed to the engine by means of a silent
block.
The standard factory setting is for a rider weighing
approximately 154.3 lbs (70 kg). For different weights
and requirements, use the pin wrench (supplied) on
the ring nut (1) to define ideal use conditions (see
chart).
Calibrate both shock absorbers to the same
position.
