SAFETY INFORMATION

EAUT1010

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 THIS
SCOOTER.
HE OR SHE SHOULD:

● OBTAIN THOROUGH INSTRUC-

TIONS FROM A COMPETENT
SOURCE ON ALL ASPECTS OF
SCOOTER OPERATION.

● OBSERVE THE WARNINGS

AND MAINTENANCE REQUIRE­MENTS IN THE OWNER’S MAN­UAL.

● OBTAIN QUALIFIED TRAINING

IN SAFE AND PROPER RIDING
TECHNIQUES.

● OBTAIN PROFESSIONAL TECH-

NICAL SERVICE AS INDICATED
BY THE OWNER’S MANUAL

AND/OR WHEN MADE NECES­SARY BY MECHANICAL CONDI­TIONS.

Safe riding

● Always make pre-operation

checks. Careful checks may help
prevent an accident.

● This scooter is designed to carry

the operator and passenger.

NOTE:

Although this scooter is designed to
carry a passenger, always comply with
the local regulations.

● The failure of motorists to detect

and recognize scooters in traffic is
the predominating 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:

• Wear a brightly colored jacket.

1-1

• Use extra caution when ap­proaching and passing through
intersections, since intersec­tions are the most likely places
for scooter accidents to occur.

• Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.

● Many accidents involve inexperi-

enced operators. In fact, many op­erators who have been involved in
accidents do not even have a cur­rent driver’s license.

• Make sure that you are qualified
and that you only lend your
scooter to other qualified opera­tors.

• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.

• We recommend that you prac­tice riding your scooter where
there is no traffic until you have
become thoroughly familiar with
the scooter and all of its con­trols.

● Many accidents have been

caused by error of the scooter op­erator. A typical error made by the

1

SAFETY INFORMATION

operator is veering wide on a turn
due to EXCESSIVE SPEED or un­der cornering (insufficient lean an-

1

gle for the speed).

• Always obey the speed limit and
never travel faster than warrant­ed by road and traffic conditions.

• Always signal before turning or
changing lanes. Make sure that
other motorists can see you.

● The posture of the operator and

passenger is important for proper
control.

• The operator should keep both
hands on the handlebar and
both feet on the footboard during
operation to maintain control of
the scooter.

• The passenger should always
hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep both
feet on the passenger footrests.

• Never carry a passenger unless
he or she can firmly place both
feet on the passenger footrests.

● Never ride under the influence of

alcohol or other drugs.

● 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.

● Always wear an approved helmet.

● Wear a face shield or goggles.

Wind in your unprotected eyes
could contribute to an impairment
of vision which could delay seeing
a hazard.

● The use of a jacket, substantial

shoes, trousers, gloves, etc., is ef­fective in preventing or reducing
abrasions or lacerations.

● Never wear loose-fitting clothes,

otherwise they could catch on the
control levers or wheels and cause
injury or an accident.

● 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.

● Passengers should also observe

the above precautions.

Modifications

Modifications made to this scooter not
approved by Yamaha, or the removal of
original equipment, may render the
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, use extreme
caution when adding cargo or accesso­ries to your scooter. Use extra care
when riding a scooter that has added
cargo or accessories. Here are some
general guidelines to follow if loading
cargo or adding accessories to your
scooter:

1-2

SAFETY INFORMATION

Loading
The total weight of the operator, pas­senger, accessories and cargo must
not exceed the maximum load limit of
180 kg (397 lb). When loading within
this weight limit, keep the following in
mind:

● Cargo and accessory weight

should be kept as low and close to
the scooter as possible. Make sure
to distribute the weight as evenly
as possible on both sides of the
scooter to minimize imbalance or
instability.

● Shifting weights can create a sud-

den imbalance. Make sure that ac­cessories and cargo are securely
attached to the scooter before
riding. Check accessory mounts
and cargo restraints frequently.

● Never attach any large or heavy

items to the handlebar, front fork,
or front fender. Such items can
create unstable handling or a slow

steering response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this scooter. Since Yamaha cannot test

all other accessories that may be avail­able, you must personally be responsi­ble for the proper selection, installation
and use of non-Yamaha accessories.
Use extreme caution when selecting
and installing any accessories.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.

● Never install accessories or carry

cargo that would impair the perfor­mance of your scooter. Carefully
inspect the accessory before using
it to make sure that 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.

1-3

• 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
passing or being passed by
large vehicles.

• 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.

● Use caution when adding electri-

cal accessories. If electrical 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

SAFETY INFORMATION

Gasoline and exhaust gas

● GASOLINE IS HIGHLY FLAMMA-

BLE:

1

• Always turn the engine off when
refueling.

• Take care not to spill any gaso­line on the engine or exhaust
system when refueling.

• Never refuel while smoking or in
the vicinity of an open flame.

● 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.

● Always turn the engine off before

leaving the scooter unattended
and remove the key from the main
switch. When parking the scooter,
note the following:

• The engine and exhaust system
may be hot, therefore, park the
scooter in a place where pedes­trians or children are not likely to
touch these hot areas.

• Do not park the scooter on a
slope or soft ground, otherwise it
may fall over.

• Do not park the scooter near a
flammable source (e.g., a kero­sene heater, or near an open
flame), otherwise it could catch
fire.

● If you should swallow any gaso-

line, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediately.
If any gasoline spills on your skin
or clothing, immediately wash the
affected area with soap and water
and change your clothes.

EAU10371

Further safe-riding points

● Be sure to signal clearly when

making turns.

● 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.

● Slow down as you approach a cor-

ner or turn. Once you have com­pleted a turn, accelerate slowly.

● Be careful when passing parked

cars. A driver might not see you
and open a door in your path.

● Railroad crossings, streetcar rails,

iron plates on road construction
sites, and manhole covers be­come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up­right, otherwise it could slide out
from under you.

● The brake pads could get wet

when you wash the scooter. After
washing the scooter, check the
brakes before riding.

1-4

● 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.

INSTRUMENT AND CONTROL FUNCTIONS

● Do not subject the shock ab-

sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.

● Do not deform or damage the

PRE-OPERATION CHECKS

EAU15591

The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec­tion, to check the following points before each ride.

NOTE:

Pre-operation checks should be made each time the vehicle 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.

EWA11150

WARNING

If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operating
the vehicle.

Engine break-in

There is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the follow­ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 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 that might
result in engine overheating must be
avoided.

EAUM2090

0–150 km (0–90 mi)

Avoid prolonged operation above 1/3
throttle. Vary the speed of the scooter
from time to time. Do not operate it at
one set throttle position.

150–500 km (90–300 mi)

Avoid prolonged operation above 1/2
throttle.

500–1000 km (300–600 mi)

Avoid cruising speeds in excess of 3/4
throttle.

ECAM1070

CAUTION:

After 1000 km (600 mi) of operation,
the final transmission oil must be

Checking the spark plug

The spark plug is an important engine
component, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode, it
should be removed and checked in ac­cordance with the periodic mainte­nance and lubrication chart. In addition,
the condition of the spark plug can re­veal the condition of the engine.
The porcelain insulator around the cen­ter electrode of the spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally). If
the spark plug shows a distinctly differ­ent color, the engine could be defec­tive. Do not attempt to diagnose such
problems yourself. Instead, have a
Yamaha dealer check the vehicle.
If the spark plug shows signs of elec­trode erosion and excessive carbon or
other deposits, it should be replaced.

Specified spark plug:

NGK/BR8HS

Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.

threads.

Tightening torque:

Spark plug:

20 Nm (2.0 m·kgf, 14.5 ft·lbf)

NOTE:

If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci­fied torque as soon as possible.

ZAUM0280

1. Minimum level mark

Insufficient brake fluid may allow air to
enter the brake system, possibly caus­ing it to become ineffective.

Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads
and/or brake system leakage. If the
brake fluid level is low, be sure to check
the brake pads for wear and the brake
system for leakage.
Observe these precautions:

● When checking the fluid level,

make sure that the top of the brake
fluid reservoir is level.

1

EAU22580

● Use only the recommended quality

brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor­mance.

Recommended brake fluid:

DOT 4

● Refill with the same type of brake

fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.

● Be careful that water does not en-

ter the brake fluid reservoir when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.

● Brake fluid may deteriorate paint-

ed surfaces or plastic parts. Al­ways clean up spilled fluid
immediately.

● As the brake pads wear, it is nor-

mal for the brake fluid level to grad­ually go down. However, if the
brake fluid level goes down sud­denly, have a Yamaha dealer
check the cause.

Troubleshooting

Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur dur­ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your­self. However, should your scooter re­quire any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the scooter prop­erly.
Use only genuine Yamaha replace­ment parts. Imitation parts may look like
Yamaha parts, but they are often inferi­or, have a shorter service life and can
lead to expensive repair bills.

SCOOTER CARE AND STORAGE

Care

While the open design of a scooter re­veals the attractiveness of the technol­ogy, it also makes it more vulnerable.
Rust and corrosion can develop even if
high-quality components are used. A
rusty exhaust pipe may go unnoticed
on a car, however, it detracts from the
overall appearance of a scooter. Fre­quent and proper care does not only
comply with the terms of the warranty,
but it will also keep your scooter looking
good, extend its life and optimize its
performance.

Before cleaning

1. Cover the muffler outlet with a

7

plastic bag after the engine has
cooled down.

2. Make sure that all caps and covers
as well as all electrical couplers
and connectors, including the
spark plug cap, are tightly in­stalled.

3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod-

EAU26090

ucts onto seals, gaskets and wheel
axles. Always rinse the dirt and de­greaser off with water.

Cleaning

ECA10780

CAUTION:

● Avoid using strong acidic wheel

cleaners, especially on spoked
wheels. If such products are
used on hard-to-remove dirt, do
not leave the cleaner on the af­fected area any longer than in­structed. Also, thoroughly rinse
the area off with water, immedi­ately dry it, and then apply a cor­rosion protection spray.

● Improper cleaning can damage

windshields, cowlings, panels
and other plastic parts. Use only
a soft, clean cloth or sponge
with mild detergent and water to
clean plastic.

● Do not use any harsh chemical

products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent or

7-1

thinner, fuel (gasoline), rust re­movers or inhibitors, brake flu­id, antifreeze or electrolyte.

● Do not use high-pressure wash-

ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar­eas: seals (of wheel and swing­arm bearings, fork and brakes),
electric components (couplers,
connectors, instruments,
switches and lights), breather
hoses and vents.

● For scooters equipped with a

windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning com­pounds for plastic may leave
scratches on the windshield.
Test the product on a small hid­den part of the windshield to
make sure that it does not leave
any marks. If the windshield is
scratched, use a quality plastic
polishing compound after
washing.

SCOOTER CARE AND STORAGE

After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning.

After riding in the rain, near the sea or
on salt-sprayed roads
Since sea salt or salt sprayed on the
roads during winter are extremely cor­rosive in combination with water, carry
out the following steps after each ride in
the rain, near the sea or on salt­sprayed roads.

NOTE:

Salt sprayed on roads in the winter may
remain well into spring.

1. Clean the scooter with cold water
and a mild detergent after the en­gine has cooled down.

ECA10790

CAUTION:

Do not use warm water since it in­creases the corrosive action of the
salt.

2. Apply a corrosion protection spray
on all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.

After cleaning

1. Dry the scooter with a chamois or
an absorbing cloth.

2. Use a chrome polish to shine
chrome, aluminum and stainless­steel parts, including the exhaust
system. (Even the thermally in­duced discoloring of stainless­steel exhaust systems can be re­moved through polishing.)

3. To prevent corrosion, it is recom­mended to apply a corrosion pro­tection spray on all metal,
including chrome- and nickel-plat­ed, surfaces.

4. Use spray oil as a universal clean­er to remove any remaining dirt.

5. Touch up minor paint damage
caused by stones, etc.

6. Wax all painted surfaces.

7. Let the scooter dry completely be­fore storing or covering it.

EWA10940

WARNING

● Make sure that there is no oil or

wax on the brakes or tires. If
necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or ac­etone, and wash the tires with
warm water and a mild deter­gent.

● Before operating the scooter

test its braking performance
and cornering behavior.

ECA10800

CAUTION:

● Apply spray oil and wax spar-

ingly and make sure to wipe off
any excess.

● Never apply oil or wax to any

rubber and plastic parts, but
treat them with a suitable care

Storage

Short-term

Always store your scooter in a cool, dry
place and, if necessary, protect it
against dust with a porous cover.

ECA10820

CAUTION:

● Storing the scooter in a poorly

ventilated room or covering it
with a tarp, while it is still wet,
will allow water and humidity to
seep in and cause rust.

● To prevent corrosion, avoid

damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi­cals are stored.

Long-term

Before storing your scooter for several
months:

1. Follow all the instructions in the
“Care” section of this chapter.

7-3

2. Drain the carburetor float chamber
by loosening the drain bolt; this will
prevent fuel deposits from building
up. Pour the drained fuel into the
fuel tank.

3. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.

4. Perform the following steps to pro­tect the cylinder, piston rings, etc.
from corrosion.
a. Remove the spark plug cap

and spark plug.

b. Pour a teaspoonful of engine oil

into the spark plug bore.

c. Install the spark plug cap onto

the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes are
grounded. (This will limit spark­ing during the next step.)

d. Turn the engine over several

times with the starter. (This will
coat the cylinder wall with oil.)

e. Remove the spark plug cap

from the spark plug, and then
install the spark plug and the
spark plug cap.

SCOOTER CARE AND STORAGE

EWA10950

WARNING

To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turning
the engine over.

5. Lubricate all control cables and the
pivoting points of all levers and
pedals as well as of the side­stand/centerstand.

6. Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alterna­tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.

7. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.

8. Remove the battery and fully
charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an ex­cessively cold or warm place [less
than 0 °C (30 °F) or more than 30

°C (90 °F)]. For more information
on storing the battery, see page
