Tires
To maximize the performance, durabi-
lity, and safe operation of your scoo-
ter, note the following points regar-
ding the specified tires.
Tire air pressure
The tire air pressure should be chec-
ked and, if necessary, adjusted befo-
re each ride.
EWA10500
s s
WARNING
●The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperatu-
re of the tires equals the
ambient temperature).
●The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passenger,
cargo, and accessories appro-
ved for this model.
EWA14660

WARNING
Because loading has an enormous
impact on the handling, braking,
performance and safety characte-
ristics of your vehicle, you shouldkeep the following precautions in
mind.
●NEVER OVERLOAD THE VEHI-
CLE! Operation of an overloa-
ded vehicle may result in tire
damage, loss of control, or
severe injury. Make sure that
the total weight of rider, pas-
senger, cargo, and accessories
does not exceed the specified
maximum load for the vehicle.
●Do not carry along loosely pac-
ked items, which can shift
during a ride.
●Securely pack the heaviest
items close to the center of the
vehicle and distribute the
weight evenly on both sides.
●Adjust the suspension and tire
air pressure with regard to the
load.
●Check the tire condition and air
pressure before each ride.
Tire air pressure (measured on
cold tires):
Up to 90 kg (198 lb):
Front:
190 kPa (28 psi) (1.90 kgf/cm

Tire inspection
1. Tire tread depth
2. Tire sidewall
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 Yama-
ha dealer replace the tire immediately.
NOTE:
The tire tread depth limits may differ
from country to country. Always
comply with the local regulations.
Tire information
This scooter is equipped with tube-
less tires.
EWA10470
s s
WARNING
●Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
vehicle with excessively worn
tires decreases riding stability
and can lead to loss of control.
●The replacement of all wheel
and brake related parts, inclu-
ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience.

Cast wheels
To maximize the performance, durabi-
lity, and safe operation of your vehi-
cle, note the following points regar-
ding the specified wheels.
●The wheel rims should be chec-
ked 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 crac-
ked wheel must be replaced.
●The 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.
●Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for
it to develop its optimal characte-
ristics.

Front and rear brake lever
free play
Front
Rear
There should be no free play at the
brake lever ends. If there is free play,
have a Yamaha dealer inspect the
brake system.
EWA14211
s s
WARNING
A soft or spongy feeling in the bra-
ke lever can indicate the presence
of air in the hydraulic system. If the-
re is air in the hydraulic system,
have a Yamaha dealer bleed the
system before operating the vehi-
cle. Air in the hydraulic system will
diminish the braking performance,
which may result in loss of control
and an accident.

Battery
This model is equipped with a sealed-
type (MF) battery, which does not
require any maintenance. There is no
need to check the electrolyte or to
add distilled water.
ECA10630
CAUTION:
●Always keep the battery char-
ged. Storing a discharged bat-
tery can cause permanent bat-
tery damage.
●To charge a sealed-type (MF)
battery, a special (constant-
voltage) battery charger is
required. Using a conventional
battery charger will damage
the battery. If you do not have
access to a sealed-type (MF)
battery charger, have a Yamaha
dealer charge your battery.

WARNING
●lectrolyte is poisonous and
dangerous since it contains
sulfuric acid, which causes
severe burns. Avoid any con-tact with skin, eyes or clothing
and always shield your eyes
when working near batteries.
In case of contact, administer
the following FIRST AID.
• EXTERNAL: Flush with plenty
of water.
• INTERNAL: Drink large quan-
tities of water or milk and
immediately call a physician.
• EYES: Flush with water for 15
minutes and seek prompt
medical attention.
●Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed spa-
ce.
●KEEP THIS AND ALL BATTE-
RIES OUT OF THE REACH OF
CHILDREN.
To charge the battery
Have a Yamaha dealer charge the
battery as soon as possible if it seems
to have discharged. Keep in mind that
