NOTE:_
The annual checks must be performed every year, except if a kilometer-based maintenance is performed instead.
From 50,000 km, repeat the maintenance intervals starting from 10,000 km.
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and techni-
cal skills.

NOTE:_
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
Hydraulic brake and clutch service
Regularly check and, if necessary, correct the brake and clutch fluid levels.
Every two years replace the internal components of the brake master cylinders and calipers as well as clutch master
and release cylinders, and change the brake and clutch fluids.

6Tire 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 side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.
CE-08ENOTE:_ The tire tread depth limits may differ
from country to country. Always comply
with the local regulations. _
EW000079
WARNING
_
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
motorcycle with excessively
worn tires decreases riding sta-
bility 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.
_
Tire information
This motorcycle is equipped with cast
wheels and tubeless tires with valves.
EW000080
WARNING
_
The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the motor-
cycle cannot be guaranteed.

proved for this model by

Clutch lever free play Since this model is equipped with a hy-
draulic clutch, adjusting the clutch lever
free play is not needed. However, it is
necessary to check the clutch fluid lev-
el and check the hydraulic system for
leakage before each ride. If the clutch
lever free play does become exces-
sive, and shifting becomes rough or
clutch slippage occurs, causing poor
acceleration, there may be air in the
clutch system. If there is air in the hy-
draulic system, have a Yamaha dealer
bleed the system before operating the
motorcycle.
EAU00712
Adjusting the brake pedal
position The top of the brake pedal should be
positioned approximately 42 mm below
the top of the footrest as shown. Peri-
odically check the brake pedal position
and, if necessary, have a Yamaha
dealer adjust it.
EW000109
WARNING
_ A soft or spongy feeling in the brake
pedal can indicate the presence of
air in the hydraulic system. If there
is air in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the motorcycle. Air in
the hydraulic system will diminish
the braking performance, which
may result in loss of control and an
accident. _

Adjusting the rear brake light
switch The rear brake light switch, which is ac-
tivated by the brake pedal, is properly
adjusted when the brake light comes
on just before braking takes effect. If
necessary, adjust the brake light switch
as follows.
Turn the adjusting nut while holding the
rear brake light switch in place. To
make the brake light come on earlier,
turn the adjusting nut in direction
a. To
make the brake light come on later,
turn the adjusting nut in direction
b.

Checking the front and rear
brake pads The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU00725
Front 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 the brake pad wear, check
the 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.

Rear brake pads
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, have a
Yamaha dealer replace the brake pads
as a set.
EAU05024
Checking the brake and clutch
fluid levels Insufficient brake fluid may allow air to
enter the brake or clutch systems, pos-
sibly causing them to become ineffec-
tive.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake flu-
id 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.
NOTE:_ The rear brake fluid reservoir is located
behind panel F. (See page 6-7 for pan-
el removal and installation proce-
dures.) _

6 Observe these precautions:
When checking the fluid level,
make sure that the top of the brake
or clutch fluid reservoir is level.
Use only the recommended quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.
The brake or clutch fluid reservoir
diaphragm will lose its shape from
the negative pressure if the fluid
level goes down too far. Be sure to
return the diaphragm to its original
shape before installing it into the
brake or clutch fluid reservoir.
Be careful that water does not en-
ter the brake or clutch fluid reser-
voir when refilling. Water will
significantly lower the boiling point
of the fluid and may result in vapor
lock, and dirt may clog the ABS
hydraulic unit valves.
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways 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 sud-
denly, have a Yamaha dealer
check the cause.
