hicle, note the following points regard-
ing the specifi ed tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EWA10503
WARNING
Operation of this vehicle with im-
proper tire pressure may cause
severe injury or death from loss of
control.● The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the tempera-
ture of the tires equals the am-
bient temperature).● The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passen-
ger, cargo, and accessories ap-
proved for this model.
Tire air pressure (measured on cold
tires):
Up to 90 kg (198 lb):
Front:
175 kPa (1.75 kgf/cm
2, 25 psi)
Rear:
200 kPa (2.00 kgf/cm2, 29 psi)

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, includ-
ing the tires, should be left to
a Yamaha dealer, who has the
necessary professional knowl-
edge and experience.
EAU21962
Cast wheelsTo maximize the performance, dura-
bility, and safe operation of your ve-
hicle, note the following points regard-
ing the specifi ed wheels.● The wheel rims should be
checked for cracks, bends, warp-
age or other damage 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.● 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.

shown. Periodically check the brake
lever free play and, if necessary, ad-

If proper adjustment cannot be ob-

Checking the brake lever free
playThere should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
EWA14211
WARNING
A soft or spongy feeling in the
brake lever can indicate the pres-
ence of air in the hydraulic system.
If there is air in the hydraulic sys-
tem, have a Yamaha dealer bleed
the system before operating the
vehicle. Air in the hydraulic system
will diminish the braking perfor-
mance, which may result in loss of
control and an accident.

to the point that the wear indicator
reaches the wear limit line, have a
Yamaha dealer replace the brake
shoes as a set.

Check the brake fluid level with the

Improper maintenance can result
in loss of braking ability. Observe

tem, reducing braking perfor-
mance.
● Clean the filler cap before re-
moving. Use only DOT 4 brake
uid from a sealed container.● Use only the specified brake
fluid; otherwise, the rubber
seals may deteriorate, causing
leakage.● Refill with the same type of
brake uid. Adding a brake u-
id other than DOT 4 may result
in a harmful chemical reaction.● Be careful that water does not
enter the brake fluid reser-
voir when refilling. Water will
significantly lower the boiling
point of the fluid and may re-
sult in vapor lock.
ECA17640
NOTICEBrake fluid may damage painted
surfaces or plastic parts. Always
clean up spilled uid immediately.
As the brake pads wear, it is normal
for the brake fluid level to gradually go down. A low brake fl uid level may
indicate worn brake pads and/or brake
system leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake
fl uid level goes down suddenly, have
a Yamaha dealer check the cause be-
fore further riding.
EAU22721
Changing the brake uidHave a Yamaha dealer change the
brake fl uid at the intervals specifi ed in
the TIP after the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the brake master cyl-
inder and caliper as well as the brake
hose replaced at the intervals listed
below or whenever they are damaged
or leaking.● Oil seals: Replace every two
years.● Brake hose: Replace every four
years.

at the intervals specifi ed in the period-
ic maintenance and lubrication chart.
EAU23095
Checking and lubricating the
cablesThe operation of all control cables
and the condition of the cables should
be checked before each ride, and
the cables and cable ends should be
lubricated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or re-
place it.
WARNING! Damage to the outer
housing of cables may result in
internal rusting and cause inter-
ference with cable movement.
Replace damaged cables as soon
as possible to prevent unsafe
conditions.
[EWA10711]
Recommended lubricant:
Yamaha Chain and Cable Lube or
engine oil
EAU23114
Checking and lubricating the
throttle grip and cableThe operation of the throttle grip
should be checked before each ride.
In addition, the cable should be lubri-
cated by a Yamaha dealer at the inter-
vals specified in the periodic mainte-
nance chart.
The throttle cable is equipped with a
rubber cover. Make sure that the cov-
er is securely installed. Even though
the cover is installed correctly, it does
not completely protect the cable from
water entry. Therefore, use care not to
pour water directly onto the cover or
cable when washing the vehicle. If the
cable or cover becomes dirty, wipe
clean with a moist cloth.
