THINK OF YOUR SAFETY

Both scooters and mopeds are fascinating vehicles which give a tremendous feeling of freedom to their riders. They

1

must be correctly maintained at all times in order to ensure optimum performance. However, as a rider you must also
ensure that your physical condition is good, and that you are not tired, in order that you too can optimize your vehicle
control. Medicines, drugs and alcohol should not be combined with riding, especially alcohol, which increases the
individual’s likelihood of taking risks. Alcohol is dangerous, even in small quantities.
Correct protective riding gear is just as much a part of motorcycling safety as the safety belt is in the car; a good leather
suit and gloves, sturdy boots and a good quality, properly fitting crash helmet are ideal. But beware: good protective
clothing can result in the individual being lulled into a false sense of security. When this happens more risks are taken
and speeds increase... this particularly applies in wet weather. The good motorcyclist therefore rides defensively and
protectively in order to minimize risks.

SAFETY INFORMATION

TWO-WHEELED SCOOTERS ARE SINGLE TRACK VEHICLES. THEIR SAFE USE AND OPERATION 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 ASPECTS 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.

5. ALWAYS RESPECT THE RELEVANT LAWS AND REGULATIONS OF EACH COUNTRY.

a. Always observe the speed limits and never go faster than the state of the road and the traffic conditions allow.
b. Always signal when turning or changing lanes. Make sure you can be seen by other road users.

a. The operator should keep both hands on the handlebars and both feet on the footboard during operation to

maintain control of the scooter.
b. The passenger should always hold on the operator, or the seat strap or grab bar if the scooter is so equipped with

both hands and keep both feet on the passenger footrests.
c. Never carry a passenger unless he or she can firmly place both feet on the passenger footrests.

GIVE SAFETY THE RIGHT OF WAY

8. Never carry any object which can cause danger if they fall off (pointed or sharp objects, for example).

9. This scooter is designed for on-road use only. It is not suitable for off-road use.

10. Always be particularly attentive when riding the scooter, and take care not to allow yourself to be distracted or
influenced by objects or people.

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.

4. Never wear loose fitting clothing. It 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.

6. A passenger should also observe the above precautions.

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 injury. 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
scooter is changed. To avoid the possibility of an accident, extreme caution should be used if adding cargo or accessories

1

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:

LOADING

The total weight of the operator, passenger, accessories and cargo must not exceed the maximum load limit of 152 kg
(335 lb).
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 possible. Be sure to distribute the
weight as evenly as possible on both sides of the machine to minimize imbalance or instability.

2. Shifting weights can create a sudden imbalance. Make sure that accessories and cargo 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.

1-5

GIVE SAFETY THE RIGHT OF WAY

ACCESSORIES

Yamaha original accessories have been specially designed for use on this scooter. Because Yamaha can not test every
accessory which is available on the market, the owner is personally responsible for the selection, fitting and use of
accessories of other makes.
The directives dealing with loading apply equally to accessories.

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.
a. 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.

b. 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 become unstable in cross winds. These accessories may also
cause instability when being passed by or passing large vehicles.

c. Certain accessories can displace the operator from his or her normal riding position. This improper position limits

the freedom of movement of the operator and may limit control ability. Therefore such accessories are not
recommended.

2. 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.

GIVE SAFETY THE RIGHT OF WAY

GASOLINE AND EXHAUST GAS

1. GASOLINE IS HIGHLY FLAMMABLE:

1

a. Always turn off the engine when refueling.
b. Take care not to spill any gasoline on the engine or exhaust pipe(s)/muffler(s) when refueling.
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 ignition key. When parking the
scooter, note the following:
a. The engine and exhaust pipe(s)/muffler(s) may be hot. Park the scooter in a place where pedestrians 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 eye(s), see your
doctor immediately. If any gasoline spills on your skin or clothing, immediately wash with soap and water and
change your clothes.

RECOMMENDATIONS IN CASE OF ACCIDENT

If the scooter has been in an accident, it is imperative that the following points are checked:

1. The good condition of the entire braking system, including the levers, cables and lines, etc ...

2. The good condition of the active or passive indicators (lights, reflectors ...)

3. The good condition of all vital components such as the frame, wheels, suspension systems, oil reservoirs, petrol
tanks, etc ...

4. Do not ride the scooter if there is any doubt about its condition or operation, and have it taken to a Yamaha dealer for
a check-up and any repairs required, pointing out all its operating faults.

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
unleaded fuel. Unleaded fuel will give
you longer spark plug life and reduced
maintenance cost. If unleaded gasoline
is not available, then leaded regular
gasoline can be used.

Gasohol
There are two types of gasohol;
gasohol containing ethanol and that
containing methanol. Gasohol
containing ethanol can be used if etha­nol content does not exceed 10%.
Gasohol containing methanol is not rec­ommended by Yamaha because it can
cause fuel system damage or vehicle
performance problems.

WARNING

Gas and oil are flammable:

• When refuelling immediately after
operation, take special care not to
spill gasoline over the engine or
muffler.

• Should you spill gasoline or oil on
the engine or muffler, quicky wipe
it off before starting the engine.

• When refuelling, be sure to stop
the engine.

• Never attempt to refuel the scoo­ter while smoking or near an open

PRE-OPERATION CHECKS

Owners are personally responsible for their vehicle’s condition. Your scooter’s vital function can start to deteriorate quickly
and unexpectedly, even if it remains unused (for instance, if it 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 thorough visual inspec­tion, you check the following points before each ride.

PRE-OPERATION CHECKS

PRE-OPERATION CHECKS

NOTE:

Pre-operation checks should be made each time the scooter is used. Such an inspection can be accomplished in a very
short time; and the added safety it assures is more than worth the time involved.

WARNING

1. The engine, exhaust pipe(s), and muffler(s) 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 inspection 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.

WARNING

The engine compartment and all the fan inlets need to stay clean and free of foreign materials.
Do not leave any rag inside or under the plastic covers of your scooter, whatever the location.

Engine break-in

There is never a more important period
in the life of your scooter than the period
between 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.

EAF32000

1. 0 ~ 150 km (0 ~ 90 mi):
Avoid operation above 1/3 throttle.
Stop the engine and let it cool for 5
to 10 minutes after every hour of
operation. Vary the speed of the
scooter from time to time. Do not
operate it at one set throttle position.

2. 150 ~ 500 km (90 ~ 300 mi):
Avoid prolonged operation above
1/2 throttle.

EUU35300

CAUTION:

After 1,000 km (600 mi) of operation,
be sure to replace the transmission
oil.

3. 500 ~ 1,000 km (300 ~ 600 mi):
Avoid cruising speeds in excess of
3/4 throttle.

4. 1,000 km (600 mi) and beyond:
Avoid prolonged full throttle
operation. Vary speeds occasionally.

1. Spark plug gap

EAH20202

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 porcelain insulator
around the center electrode 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 because
heat and deposits will cause the spark
plug to slowly break down and erode.

If electrode erosion becomes exces­sive, or if carbon and other deposits are
excessive, you should replace the
spark plugs with the specified plug.

Standard spark plug:

BR8HS (NGK)

Before installing the spark plug,
measure the electrode gap with a wire
thickness gauge and adjust the gap to
specification as necessary.

Spark plug gap:

0.5 ~ 0.7 mm (0.020 ~ 0.031 in)

When installing the plug, always clean
the gasket surface and use a new
gasket. Wipe off any grime from the
threads and tighten the spark plug to
the specified torque.

Tightening torque:

Spark plug:

20 Nm (2.0 m·kg, 14 ft·lb)

EUU03801

NOTE:

If a torque wrench is not available when
you are installing a spark plug, a good
estimate of the correct torque is 1/4 to
1/2 turn past finger tight. Have the spark
plug torqued to the correct value as
soon as possible with a torque wrench.

Observe these precautions:

1. When checking the fluid level, make
sure the top of the master cylinder is
level by turning the handlebars.

2. Use only the designated quality
brake fluid. Otherwise, the rubber
seals may deteriorate, causing
leakage and poor brake perfor­mance.

Recommended brake fluid:

DOT #3 or DOT #4

3. Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and lead
to poor brake performance.

4. Be careful that water does not enter
the master cylinder when refilling.
Water will significantly lower the
boiling point of the fluid and may
result in “VAPOR LOCK”.

5. Brake fluid may deteriorate painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.

6. Have a Yamaha dealer check the
cause if the brake fluid level goes
down.

Troubleshooting

Although Yamaha scooters receive a
rigid inspection before shipment from
the factory, 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, experience, and know­how to properly service 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
expensive repair bills.

SCOOTER CARE AND STORAGE

:

A. CLEANING

Frequent, thorough cleaning of your
scooter will not only enhance its
appearance but will improve its general
performance and extend the useful life
of many components.

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.

b. Make sure the spark plug(s) and

all filler caps are properly
installed.

2. If the engine case is excessively

8

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
pressure to do the job.

EAK01102

EUU34602

CAUTION:

Excessive hose pressure may cause
water seepage and deterioration of
wheel bearings, front fork, brakes,
transmission seals and electrical
devices. Many expensive repair bills
have resulted from improper high
pressure detergent applications
such as those available in coin­operated car washers.

4. Once the majority of the dirt has
been hosed off, wash all surfaces
with warm water and mild, detergent­type soap. An old toothbrush or bottle
brush is handy for hard-to-get-at pla­ces.

5. Rinse the scooter off immediately
with clean water and dry all surfa­ces with a chamois, clean towel, or
soft absorbent cloth.

6. Clean the seat with a vinyl upholstery
cleaner to keep the cover pliable and
glossy.

7. Automotive-type wax may be applied
to all painted and chrome-plated sur­faces. Avoid combination cleaner­waxes. Many contain abrasives
which may mar the paint or
protective finish. When finished, start
the engine and let it idle for several
minutes.

CAUTION

All of the fan inlets need to be clean
and free from foreign materials.

8-1

SCOOTER CARE AND STORAGE

EAK01500

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, prepare for storage as
follows:

1. Drain the fuel tank, fuel lines, and
carburetor float bowl(s).

2. 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. Kick
the engine over several times (with
the ignition off) to coat the cylinder
walls with oil.

EUU66400

WARNING

When using the starter motor to
crank the engine, remove the spark
plug wires, and ground them to
prevent sparking.

3. Lubricate all control cables.

4. Block up the frame to raise both
wheels off the ground.

5. Tie a plastic bag over the exhaust
pipe outlet to prevent moisture from
entering.

6. If storing in a humid or salt-air
atmosphere, coat all exposed metal
surfaces with a light film of oil. Do
not apply oil to any rubber parts or
the seat cover.

7. Remove the battery and charge it.
Store it in a dry place and recharge
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)).

Keep your Yamaha protected even after your warranty ex­pires with genuine Yamaha Extended Service (Y.E.S.).

• Y.E.S. is designed and administered by Yamaha Motor
Corporation to provide maximum owner satisfaction. You
get uninterrupted factory-backed coverage for extra
peace of mind.

• Y.E.S. is flexible. You choose the plan that’s right for
you: 12 months, 24 months, or 36 months beyond your
warranty period.

• Y.E.S. is designed and administered by the same
Yamaha people who handle your warranty - and it shows
in the comprehensive coverage benefits. There are no
mileage limitations. Coverage isn’t limited to “moving
parts” or the “drive train” like many other plans. And Y.E.S.
covers manufacturing defects just like the warranty. See
the sample contract at your Yamaha dealer to see how
comforting uninterrupted factory-backed protection can
be.

• You don’t have to pay anything for covered repairs.
There’s no deductible to pay, and repairs aren’t “pro­rated”. You don’t have any “out-of-pocket” expenses for
covered repairs.

• In addition, Travel and Recreation Interruption Protec­tion (TRIP) is included at no extra cost. TRIP gives you
up to $150 reimbursement per occurrence for any
reasonable expenses you incur because your Yamaha
needs covered service : replacement vehicle rental,
emergency towing, phone calls, even food and lodging
when you are away from home. This superb coverage
goes into effect when you purchase Y.E.S., so it applies
to any warranty repairs as well as covered repairs during
your entire Y.E.S. plan period.

• Y.E.S. coverage is honored at any authorized Yamaha
dealer nationwide.

• Y.E.S. coverage is transferrable to a new owner if you
sell or trade-in. That can make your Yamaha much more
valuable !

This excellent Y.E.S. plan coverage is only available to
Yamaha owners like you, and only while your Yamaha is
still within the Yamaha Limited Warranty period. So visit
your authorized Yamaha dealer to get all the facts. He
can show you how easy it is to protect your investment
with Yamaha Extended Service.

10-7

We urge you to act now. You’ll get the excellent benefits
of TRIP coverage right away, and you’ll rest easy knowing
you’ll have strong factory-backed protection even after
your Yamaha Limited Warranty expires. You can also save
money : Y.E.S. costs less within the first 90 days after you
buy your Yamaha. See your dealer today !

A special note :
If visiting your dealer isn’t convenient, contact Yamaha
with your Primary ID number (your frame number). We’ll
be happy to help you get the Y.E.S. coverage you need.
