Hydraulic brake and clutch systems
• After disassembling the brake or clutch master cylinders, caliper cylinders or clutch release cylinder, always change
the fluid. Regularly check the brake and clutch fluid levels and fill the reservoirs as required.
• Replace the oil seals on the inner parts of the brake or clutch master cylinders, caliper cylinders and clutch release
cylinder every two years.
• Replace the brake and clutch hoses every four years or if cracked or damaged.

WARNING
_ l
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.
l
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 tube-
less tires, tire air valves and cast
wheels.
EW000132
WARNING
_ l
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.
l
After extensive tests, only the
tires listed below have been ap-
proved for this model by
Yamaha Motor Co., Ltd.
l
Always make sure that the valve
caps are securely installed to
prevent air pressure leakage.
l
Use only the tire valves and
valve cores listed below to
avoid tire deflation during a
ride.

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.
EAU00696
Adjusting the brake lever free
play The brake lever free play should mea-
sure 2–5 mm as shown. Periodically
check the brake lever free play and, if
necessary, adjust it as follows.
1. Loosen the locknut at the brake
lever.
2. To increase the brake lever free
play, turn the adjusting bolt in di-
rection
a. To decrease the brake
lever free play, turn the adjusting
bolt in direction
b.3. Tighten the locknut.
EW000099
WARNING
@ l
After adjusting the brake lever
free play, check the free play
and make sure that the brake is
working properly.
l
A soft or spongy feeling in the
brake lever can indicate the
presence of air in the hydraulic
system. If there is air in the hy-
draulic system, have a Yamaha
dealer bleed the system before
operating the motorcycle. Air in
the hydraulic system will dimin-
ish the braking performance,
which may result in loss of con-
trol and an accident.

Adjusting the brake pedal
position The top of the brake pedal should be
positioned approximately 100 mm
above the top of the footrest as shown.
Periodically check the brake pedal po-
sition 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.
Since the brake light switch is a compo-
nent of the cruise control system, it
must be adjusted by a Yamaha dealer,
who has the necessary professional
knowledge and experience.

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.
EAU03938
Front brake pads
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear with-
out 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 disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
EAU03939
Rear brake pads
Each rear 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.

Checking the brake and clutch
fluid levels Insufficient brake or clutch fluid may al-
low air to enter the brake or clutch sys-
tems, possibly causing them to
become ineffective.
Before riding, check that the brake and
clutch fluids are above the minimum
level marks and replenish if necessary.
A low brake or clutch fluid level may in-
dicate brake or clutch system leakage
and/or worn brake pads. If the brake or
clutch levels are low, be sure to check
the brake or clutch systems for leakage
and the brake pads for wear.Observe these precautions:
l
When checking the brake and
clutch fluid levels, make sure that
the top of each reservoir is level.
l
Use only the recommended quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.
l
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.
l
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.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
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.
