6 Tire inspection
The tires must be checked before
each ride. If the center tread depth
reaches the specified limit, if the tire
has a nail or glass fragments in it, or
if the sidewall is cracked, have a
Yamaha dealer replace the tire imme-
diately.
NOTE:
The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.

Have a Yamaha dealer replace
excessively worn tires.
Besides being illegal, operat-
ing the scooter with exces-
sively worn tires decreases
riding stability and can lead to
loss of control.
8 8
The replacement of all wheel
and brake related parts,
including the tires, should be
left to a Yamaha dealer, who
has the necessary profession-
al knowledge and experience.
Tire information
This scooter is equipped with cast
wheels and tubeless tires.

Cast wheelsWheels
To maximize the performance, dura-
bility, and safe operation of your
scooter, note the following points
regarding the specified wheels.
8The wheel rims should be
checked for cracks, bends or
warpage before each ride. If any
damage is found, have a
Yamaha dealer replace the
wheel. Do not attempt even the
smallest repair to the wheel. A
deformed or cracked wheel must
be replaced.
8The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced.
An unbalanced wheel can result
in poor performance, adverse
handling characteristics, and a
shortened tire life.
EAU03851
Front and rear brake levers
There should be no free play at the
brake lever ends. If there is free play,
have a Yamaha dealer inspect the
brake system.
8Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for
it to develop its optimal charac-
teristics.FRONT

Front brake pads
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear
without having to disassemble the
brake. To check the brake pad wear,
check the wear indicator grooves. If a
brake pad has worn to the point that
the wear indicator grooves have
almost disappeared, have a Yamaha
dealer replace the brake pads as a
set.

Rear brake pads
1. Remove the rear brake caliper
by removing the bolts.
2. Check each rear brake pad for
damage and measure the lining
thickness. If a brake pad is dam-
aged or if the lining thickness is
less than 0.8 mm, have a
Yamaha dealer replace the
brake pads as a set.
3. Install the rear brake caliper by
installing the bolts, then tighten-
ing them to the specified torque.

Checking the brake fluid
level
Brake fluid level, checking
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 leak-
age.

6 Observe these precautions:
8When checking the fluid level,
make sure that the top of the
brake fluid reservoir is level.
8Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.

Changing the brake fluidBrake fluid, changing
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addi-
tion, have the oil seals of the master
cylinders and calipers as well as the
brake hoses replaced at the intervals
listed below or whenever they are
damaged or leaking.
8Oil seals: Replace every two
years.
8Brake hoses: Replace every four
years. 8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As 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.

To check the operation
1. Place the scooter on a level sur-
face and hold it in an upright
position.
2. While applying the front brake,
push down hard on the handle-
bars several times to check if the
front fork compresses and
rebounds smoothly.

SCOOTER CARE AND STORAGE
7 8 8
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 abra-
sive cleaning products, sol-
vent or thinner, fuel (gasoline),
rust removers or inhibitors,
brake fluid, antifreeze or elec-
trolyte.
8 8
Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the
following areas: seals (of
wheel and swingarm bearings,
fork and brakes), electric com-
ponents (couplers, connec-
tors, instruments, switches
and lights), breather hoses
and vents.8 8
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 wind-
shield. Test the product on a
small hidden part of the wind-
shield to make sure that it
does not leave any marks. If
the windshield is scratched,
use a quality plastic polishing
compound after washing.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 bottle-
brush 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
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 salt-sprayed 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.
ECA00012
cC
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, sur-
faces to prevent corrosion.
