A SAFETY INFORMATION
TWO-WHEELED SCOOTERS ARE SINGLE TRACK VEHICLES. THEIR SAFE USE AND OP-
ERATION ARE DEPENDENT UPON THE USE OF PROPER RIDING TECHNIQUES AS
WELL AS THE EXPERTISE OF THE OPERATOR.
EVERY OPERATOR SHOULD KNOW THE FOLLOWING REQUIREMENTS BEFORE
RIDING.
HE OR SHE SHOULD:
1. OBTAIN THOROUGH INSTRUCTIONS FROM A COMPETENT SOURCE ON ALL AS-
PECTS OF SCOOTER OPERATION.
2. OBSERVE THE WARNINGS AND MAINTENANCE REQUIREMENTS IN THE OWNER'S
MANUAL.
3. OBTAIN QUALIFIED TRAINING IN SAFE AND PROPER RIDING TECHNIQUES.
4. OBTAIN PROFESSIONAL TECHNICAL SERVICE AS INDICATED BY THE OWNER'S
MANUAL AND/OR WHEN MADE NECESSARY BY MECHANICAL CONDITIONS.
SAFE RIDING
1. Always make pre-operation checks. Careful checks may help prevent an accident.
2. This scooter is designed to carry the operator only. No passengers.
1-1
3. The failure of motorists to detect and recognize scooters in traffic is the predominat-
ing cause of automobile/scooter accidents. Many accidents have been caused by an
automobile driver who did not see the scooter. Making yourself conspicuous appears
to be very effective in reducing the chance of this type of accident.
Therefore:
a. Wear a brightly colored jacket.
b. Use extra caution when you approach and pass through intersections, since inter-
sections are the most likely places for scooter accidents.
с. Ride where other motorists can see you. Avoid riding in another motorists “blind
spot”.
4. Many accidents involve inexperienced operators. In fact, many operators who have
been involved in accidents do not even have a current driver's license.
a. Make sure you are qualified. Also, only lend your scooter to experienced opera-
tors.
b. Know your skills and limits. Staying within your limits may help you to avoid an
accident.
c. We recommend that you practice riding your scooter where there is no traffic un-
til you have become thoroughly familiar with your scooter and all of its controls.
5. Many scooter accidents have been caused by scooter operator errors. A typical error
made by the operator is veering wide on a turn due to EXCESSIVE SPEED or under-
cornering (insufficient lean angle for the speed).
1-2
a. Always obey the speed limits and never travel faster than warranted by road and
traffic conditions.
b. Always signal before turning or changing lanes. Make sure other motorists see
you.
6. The operator's posture is important for proper control. The operator should keep
both hands on the handlebars and both feet on the footboard during operation to
maintain control of the scooter.
7. Never ride under the influence of alcohol or drugs.
8. This scooter is designed for on-road use only. It is not suitable for off-road use.
PROTECTIVE APPAREL
The majority of fatalities from scooter accidents are the result of head injuries. The use
of a safety helmet is the single most critical factor in the prevention or reduction of head
injuries.
1. Always wear an approved helmet.
2. Wear a face shield or goggles. Wind on your unprotected eyes could contribute to an
impairment of vision which could delay seeing a hazard.
3. The use of substantial shoes, jacket, trousers, gloves, etc. is effective in preventing
or reducing abrasions or lacerations.
1-3
4. Never wear loose fitting clothing. lit could catch on the control levers or wheels and
cause injury or accident.
5. Never touch the engine or exhaust system during or after operation. They become
very hot and can cause burns. Always wear protective clothing that covers your legs,
ankles, and feet.
MODIFICATION
Modifications made to the scooter not approved by Yamaha, or the removal of original
equipment, may render your scooter unsafe for use and may cause severe personal in-
jury. Modifications may also make your scooter illegal to use.
LOADING AND ACCESSORIES
Adding accessories or cargo to your scooter can adversely affect stability and handling
if the weight distribution of the machine is changed. To avoid the possibility of an acci-
dent, extreme caution should be used if adding cargo or accessories to your scooter.
Use extra care if riding a scooter which has added cargo or accessories. Here are some
general guidelines to follow if loading cargo or adding accessories to your scooter:
1-4
The total weight of the operator, accessories and cargo must not exceed the maximum
load limit of 165 Ibs. (75 kg). |
When loading within these weight limits, keep the following in mind:
1. Cargo and accessory weight should be kept as low and close to the scooter as pos-
sible. Be sure to distribute the weight as evenly as possible on both sides of the ma-
chine to minimize imbalance or instability. |
2. Shifting weights can create a sudden imbalance. Make sure that accessories and car-
go are securely attached to the scooter before riding. Recheck accessory mounts and
cargo restraints frequently.
3. Never attach any large or heavy items to the handlebars, front forks, or front fender.
These items can create unstable handling or slow steering response.
ACCESSORIES
Genuine Yamaha accessories have been specifically designed for use on this scooter.
Since Yamaha cannot test all other accessories which may be available, you must per-
sonally be responsible for the proper selection, installation and use of non-Yamaha ac-
cessories. You should use extreme caution when selecting and installing any
accessories.
1-5
Keep in mind these guidelines for mounting accessories in addition to those provided
under “LOADING”.
1. Never install accessories or carry cargo that would impair the performance of your
scooter. Carefully inspect the accessory before using it to make sure it does not in
any way reduce ground clearance or cornering clearance, limit suspension travel,
steering travel or control operation, or obscure lights or reflectors.
Accessories fitted to the handlebar or the front fork area can create instability due
to improper weight distribution or aerodynamic changes. If accessories are added
to the handlebar or front fork area, they must be as lightweight as possible and
should be kept to a minimum.
Bulky or large accessories may seriously affect the stability of the scooter due to
aerodynamic effects. Wind may attempt to lift the scooter, or the scooter may be-
come unstable in cross winds. These accessories may also cause instability when
being passed by or passing large vehicles.
Certain accessories can displace the operator from his or her normal riding posi-
tion. This improper position limits the freedom of movement of the operator and
may limit control ability. Therefore such accessories are not recommended.
. Caution must be used if adding electrical accessories. If these accessories exceed the
capacity of the scooter's electrical system, an electric failure could result, which
could cause a dangerous loss of lights or engine power.
1-6
GASOLINE AND EXHAUST GAS
1. GASOLINE IS HIGHLY FLAMMABLE:
a. Always turn off the engine when refueling.
b. Take care not to spill any gasoline on the engine or exhaust system when refuel-
ing.
c. Never refuel while smoking or in the vicinity of an open flame.
2. Never start the engine or let it run for any length of time in a closed area. The exhaust
fumes are poisonous and may cause loss of consciousness and death within a short
time. Always operate your scooter in an area that has adequate ventilation.
3. Always turn off the engine before leaving the scooter unattended and remove the ig-
nition key. When parking the scooter, note the following:
a. The engine and exhaust system may be hot. Park the scooter in a place where pe-
destrians or children are not likely to touch these hot areas.
b. Do not park the scooter on a slope or soft ground; the scooter may fall over.
c. Do not park the scooter near a flammable source, e.g. a kerosene heater, or near
an open flame. The scooter could catch fire.
4. If you should swallow any gasoline, inhale a lot of gasoline vapor, or allow gasoline
to get in your eyes, see your doctor immediately. If any gasoline spills on your skin
or clothing, immediately wash with soap and water and change your clothes.
1-7
EAA90001
FURTHER SAFE RIDING POINTS FOR THIS MODEL
1. Be sure to signal clearly in the following instances:
Turning right = Turning left
2. Braking can be extremely difficult on a wet road. Avoid hard braking, because the
scooter could slide. Apply the brakes slowly when stopping on a wet surface.
3. Slow down as you approach a corner or turn. Once you have completed a turn, ac-
celerate slowly.
4. Be careful when passing parked cars. A driver might not see you and open a door in
your path.
2-1
. Street car rails, iron plates on road construction sites, and man-hole covers become
extremely slippery when wet. Slow down and cross them with caution. Keep the
scooter upright. It could slide out from under you.
. The brake lining could get wet when you wash the scooter. After washing the scoot-
er, check the brakes before riding.
. Always wear a helmet, gloves, trousers (tapered around the cuff and ankle so they
do not flap), and a bright colored jacket.
. Do not carry too much luggage on the scooter. An overloaded scooter is unstable. Re-
fer to “SAFETY INFORMATION” for instructions about carrying luggage. Use a
strong cord to secure any luggage to the luggage racks. A loose load will affect the
stability of the scooter and could divert your attention from the road.

PRE-OPERATION CHECKS
Owners are personally responsible for their vehicle's condition. Your scooter’s vital func-
tions can start to deteriorate quickly and unexpectedly, even if it remains unused (for in-
stance, if it is exposed to the elements). Any damage, fluid leak or loss of tire pressure
could have serious consequences. Therefore, it is very important that, in addition to a thor-
ough visual inspection, you check the following points before each ride.

NOTE:
Pre-operation checks should be made each time the scooter is used. Such an inspection
can be thoroughly accomplished in a very short time, and the added safety it assures is
more than worth the time involved.
ÁN WARNING
1. The engine, exhaust pipe, and muffler will be very hot after the engine has been run.
Be careful not to touch them or to allow any clothing item to contact them during in-
spection or repair.
2. If any item in the PRE-OPERATION CHECK is not working properly, have it inspected
and repaired before operating the scooter. If necessary ask a Yamaha dealer.

Tires
Check both front and rear tire pressures.
Also check for nails, fragments of glass, or
stones embedded in the tire treads. Check
the run-out of each tire rim, and recondi-
tion as necessary. Ask a Yamaha dealer, if
required.
EUU73702
ÁN WARNING
1. Proper loading is important for several
characteristics of your scooter; such as
handling, braking, performance and
safety. NEVER OVERLOAD YOUR
SCOOTER. Make sure the total weight
of the cargo, rider, and accessories
(fairing, saddlebags, etc. if approved for
this model) does not exceed the maxi-
mum load of the scooter. Operation of
an overloaded scooter could cause tire
damage, an accident, or even injury.
7-6
2.
Improper tire pressure greatly affects
tire life and handling. Check the pres-
sure of both tires prior to each trip
and adjust properly if necessary. If tire
pressure is too high, shocks from the
road will not be damped and will be
carried to the frame and handlebars,
thus adversely affecting riding com-
fort. In addition, scooter stability will
be poor when making a turn. If tire
pressure is too low, tires will be de-
formed greatly, thus shortening tire
life. When braking, the tires could slip
over the wheel rims and the tubes
could be damaged. Also, when turn-
ing a corner or going around a curve,
the scooter could easily turn over.
7-7
Cold tire pressure:
Front:
125 kPa (1.25 kgf/em*, 18 psi)
Rear:
175 kPa (1.75 kgf/em”, 25 psi)
Maximum loading limit*:
75 kg (165 Ib)
* Load is the total weight of cargo, rider and accessories.
If tire treads are excessively worn, the
scooter tends to slip or skid on wet roads
or even on paved roads covered with dirt.
If a tread depth shows crosswise lines, it
means that the tire is worn to its limit. Re-
place the tire.
Wear indicator
Minimum tire tread depth
(front and rear) 1.0 mm (0.04 in)
EUU68001
AN WARNING
It is dangerous to ride with a worn-out tire.
When a tire tread begins to show lines,
have a Yamaha dealer replace the tire im-
mediately. Brakes, tires and related wheel
parts replacement should also be left to a
Yamaha dealer.

UNLEADED FUEL
Fuel tank capacity:
Total:
3.5 L (0.77 Imp gal, 0.92 US gal)
Your Yamaha engine has been designed to
use regular unleaded gasoline with a
pump octane number ([R+M]/2) of 86 or
- higher, or research octane number of 91 or
higher. If knocking or pinging occurs, use a
different brand of gasoline or premium un-
leaded fuel. Unleaded fuel will give you
longer spark plug life and reduced mainte-
nance cost. If unleaded gasoline is not
available, then leaded regular gasoline can
be used.

Engine break-in
There is never a more important period in
the life of your scooter than the period be-
tween zero and 1,000 km (600 mi). For this
reason we ask that you carefully read the
following material. Because the engine is
brand new, you must not put an excessive
load on it for the first 1,000 km (600 mi).
The various parts in the engine wear and
polish themselves to the correct operating
clearances. During this period, prolonged
full throttle operation, or any condition
which might result in excessive heating of
the engine, must be avoided.

Spark plug inspection
The spark plug is an important engine
component and is easy to inspect. The
condition of the spark plug can indicate the
condition of the engine. The ideal color on
the white insulator around the center elec-
trode is a medium-to-light tan color for a
scooter that is being ridden normally. Do
not attempt to diagnose any problems
yourself. Instead, take the scooter to a
Yamaha dealer. You should periodically
remove and inspect the spark plug be-
cause heat and deposits will cause the
spark plug to slowly break down and
erode. If electrode erosion becomes exces-
sive, or if carbon and other deposits are ex-
cessive, you should replace the spark plug
with the specified plug.
Specified spark plug:
BR7HS (NGK)
Before installing the spark plug, measure
the electrode gap with a wire thickness
gauge; adjust the gap to specification as
necessary.
Spark plug gap:
0.5 - 0.6 mm (0.020 ~ 0.024 in)

Troubleshooting
Although Yamaha scooters receive a rigid
inspection before shipment from the facto-
ry, trouble may occur during operation.
Any problem in the fuel, compression, or
ignition systems can cause poor starting
and loss of power. The troubleshooting
chart describes a quick, easy procedure for
making checks.
If your scooter requires any repair, bring it
to a Yamaha dealer. The skilled technicians
at a Yamaha dealership have the tools, ex-
perience, and know-how to properly ser-
vice your scooter. Use only genuine
Yamaha parts on your scooter. Imitation
parts may look like Yamaha parts, but they
are often inferior. Consequently, they have
a shorter service life and can lead to expen-
sive repair bills.

CLEANING AND
STORAGE
EAK01104
A. CLEANING
Frequent, thorough cleaning of your scoot-
er will not only enhance its appearance but
will improve its general performance and
extend the useful life of many compo-
nents.
1. Before cleaning the scooter:
a. Block off the end of the exhaust pipe to
prevent water entry; a plastic bag and
strong rubber band may be used.
Make sure the spark plug and all filler
caps are properly installed.
2. If the engine case is excessively
greasy, apply degreaser with a paint
brush. Do not apply degreaser to
wheel axles.
3. Rinse the dirt and degreaser off with a
garden hose. Use only enough pres-
sure to do the job.
10-1
EUU34602
Excessive hose pressure may cause water
seepage and deterioration of wheel bear-
ings, front fork, brakes, transmission seals
and electrical parts.
Many expensive repair bills have resulted
from improper high pressure detergent
applications such as those available in
coin-operated car washers.
4. After riding on salted roads, wash the
scooter with cold water immediately.
Do not use warm water as it increases
the chemical reaction of the salt.
5. Once the majority of the dirt has been
hosed off, wash all surfaces with
warm water and mild, detergent-type
soap. An old toothbrush or bottle
brush is handy for hard-to-get-at plac-
es.
6. Rinse the scooter off immediately with
clean water and dry all surfaces with a
chamois, clean towel, or soft absor-
bent cloth.
Clean the seat with a vinyl upholstery
cleaner to keep the cover pliable and
glossy.
Automotive-type wax may be applied
to all painted and chrome-plated sur-
faces. Avoid combination cleaner-
waxes. Many contain abrasives which
may mar the paint or protective finish.
When finished, start the engine and let
it idle for several minutes.
EAK01502
B. STORAGE
Long term storage (60 days or more) of
your scooter will require some preventive
procedures to guard against deterioration.
After thoroughly cleaning the scooter, pre-
pare for storage as follows:
10-2
1. Fill the fuel tank with fuel and fuel sta-
bilizer (if available).
Remove the spark plug, pour about
one tablespoon of SAE 10W30 or
20W40 motor oil in the spark plug hole
and reinstall the spark plug. Turn the
engine over several times (with the ig-
nition off) to coat the cylinder wall with
oil.
EUU81400
A WARNING
When using the starter motor to crank the
engine, remove the spark plug wire, and
ground it to prevent sparking.
3.
4.
Lubricate all control cables.
Block up the frame to raise both
wheels off the ground.
Tie a plastic bag over the exhaust pipe
outlet to prevent moisture from enter-
ing.
5.
6. If storing in a humid or salt-air atmo-
sphere, coat all exposed metal surfac-
es with a light film of oil. Do not apply
oll to any rubber parts or the seat cov-
er.
7. Remove the battery and fully charge it.
Store it in a cool, dry place and re-
charge it once a month. Do not store
the battery in an excessively warm or
cold place (less than 0°C (30°F) or more
than 30°C (90°F)). See page 9-11 for
battery storage precautions.

WARRANTY QUESTIONS AND ANSWERS
What costs are my responsibility during the warranty period?
The customer's responsibility includes all costs of normal maintenance services, non-
warranty repairs, accident and collision damage, and oil, oil filters, air filters, spark
plugs, and brake shoes or pads.
What are some examples of “abnormal” strain, neglect, or abuse?
These terms are general and overlap each other in areas. Specific examples include:
Running the machine out of oil; sustained high-rpm, full-throttie use; operating the
machine with a broken or damaged part which causes another part to fail, damage
or failure due to improper or careless transporation and or tie down; and so on. If
you have any specific questions on operation or maintenance, please contact your
dealer for advice.
Does the warranty cover incidental costs such as towing or transportation due to
a failure?
No. The warranty is limited to repair of the machine itself.
May | perform any or all of the recommended maintenance shown in the Owner's
Manual instead of having the dealer do them?
Yes, if you are a qualified mechanic and follow the procedures specified in the Owner's
and Service Manual. We do recommend, however, that items requiring special tools
or equipment be done by a Yamaha Riva dealer.
Will the warranty be void or cancelled if | do not operate or maintain my new Riva
exactly as specified in the Owner's Manual?
No. The warranty on a new Riva cannot be “voided” or “cancelled.” However, if a
particular failure is caused by operation or maintenance other than as shown in the
Owner's Manual, that failure may not be covered under warranty.
What responsibility does my dealer have under this warranty?
Each Yamaha Riva dealer is expected to:
1. Completely set up every new machine before sale.
2. Explain the operation, maintenance, and warranty requirements to your satisfa-
tion at the time of sale, and upon your request at any later date.
3. In addition, each Yamaha Riva dealer is held responsible for his setup, service and
warranty repair work.
Is the warranty transferable to second owners?
Yes. The remainder of the existing warranty can be transferred upon request. The
unit has to be inspected and re-registered by an authorized Yamaha Riva dealer for
the warranty coverage to remain effective.
