Cast wheels
To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified 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 de-
formed 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 han-
dling characteristics, and a short-
ened tire life.

Clutch lever
Since this model is equipped with a hy-
draulic clutch, adjusting the clutch le-
ver free play is not needed. However, it
is necessary to check the clutch fluid
level and check the hydraulic system
for leakage. (See page 6-26.)
TIP
If clutch lever free play become exces-
sive, shifting becomes rough, or clutch
slippage occurs, there may be air in the
clutch system. Have a Yamaha dealer
bleed or replace the hydraulic clutch
fluid.

Checkin g the brake lever free
play
There should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14212
A soft or spon gy feelin g in the b rake
lever can in dicate the presence of
air in the hy draulic system. If there is
air in the hy draulic system, have a
Yamaha dealer blee d the system be-
fore operatin g the vehicle. Air in the
hy draulic system will diminish the
b rakin g performance, which may re-
sult in loss of control and an acci-
d ent.

Brake li ght switches
The brake light should come on just
before braking takes effect. The brake
light is activated by switches connect-
ed to the brake lever and brake pedal.
Since the brake light switches are
components of the anti-lock brake sys-
tem, they should only be serviced by a
Yamaha dealer.

Checkin g the front an d rear
b rake pa ds
The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU43432Front brake pa ds
The front brake calipers are equipped
with two sets of brake pads.
Each front brake pad is provided with a
wear indicator groove, which allows
you to check the brake pad wear with-
out having to disassemble the brake.
To check a brake pad for wear, check
its wear indicator groove. If a brake
pad has worn to the point that the wear
indicator groove has almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
EAU22501Rear brake pa ds
Check each rear brake pad for damage
and measure the lining thickness. If a
brake pad is damaged or if the lining
thickness is less than 0.8 mm (0.03 in),
have a Yamaha dealer replace the
brake pads as a set.

Checkin g the brake an d

Before riding, check that the brake and
clutch fluids are above the minimum
level marks. Check the brake and
clutch fluid levels with the tops of the
reservoirs level. Replenish the brake
and clutch fluids if necessary.

TIP
The rear brake fluid reservoir is located

WARNING
EWA16031
Improper maintenance can result in
loss of b
raking a bility or clutch oper-
ation. O bserve these precautions:
Insufficient brake or clutch flui d
may allow air to enter the brake
or clutch system, re ducing
b rakin g or clutch performance.
Clean the filler caps before re-
moving . Use only DOT 4 brake
flui d from a seale d container.
Use only the specified b rake flu-
i d ; otherwise, the ru bber seals
may deteriorate, causin g leak-
a g e.
Refill with the same type of
brake flui d. A ddin g a brake flui d
other than DOT 4 may result in a
harmful chemical reaction.
Be careful that water or dust
d oes not enter the brake or
clutch flui d reservoir when refill-
in g. Water will si gnificantly low-

NOTICE
ECA17641
Brake flui d may damag e painte d
surfaces or plastic parts. Always
clean up spille d flui d imme diately.
The brake or clutch fluid reservoir dia-
phragm will lose its shape from the
negative pressure if the fluid level goes
down too far. Be sure to return the dia-
phragm to its original shape before in-
stalling it into the brake or clutch fluid
reservoir.
As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake
system leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. A low clutch
fluid level may indicate clutch system
leakage; therefore, be sure to check
the clutch system for leakage. If the
brake or clutch fluid level goes down
suddenly, have a Yamaha dealer check
the cause before further riding.
EAU22754
Chan gin g the brake an d
clutch flui ds
Have a Yamaha dealer change the
brake and clutch fluids at the intervals
specified in the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the brake and clutch
master cylinders and calipers as well
as the brake and clutch hoses replaced
at the intervals listed below or whenev-
er they are damaged or leaking.
Oil seals: Replace every two
years.
Brake and clutch hoses: Replace
every four years.

The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubri-
cated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or re-
place it. WARNING! Dama ge to the
outer housin g of cab les may result
in internal rustin g an d cause inter-
ference with ca ble movement. Re-
place damag ed cab les as soon as
possi ble to prevent unsafe con di-
tions.

Checkin
g an d lu bricatin g the
throttle grip an d cab le
The operation of the throttle grip
should be checked before each ride. In
addition, the cable should be lubricat-
ed by a Yamaha dealer at the intervals
specified in the periodic maintenance
chart.
The throttle cable is equipped with a
rubber cover. Make sure that the cover
is securely installed. Even though the
cover is installed correctly, it does not
completely protect the cable from wa-
ter 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.

Yamaha cable lubricant or other
suitable cable lubricant
