Spoke wheels
To maximize the performance, dura-
bility, and safe operation of your
motorcycle, note the following points
regarding the specified wheels.
8The wheel rims should be
checked for cracks, bends or
warpage, and the spokes for
looseness or 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.
8The 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.

8After adjusting the brake lever
free play, check the free play
and make sure that the brake
is working properly.
8A soft or spongy feeling in the
brake lever 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 before operating the
motorcycle. Air in the
hydraulic system will diminish
the braking performance,
which may result in loss of
control and an accident.

Checking the front brake
pads and rear brake shoes
The front brake pads and the rear
brake shoes must be checked for
wear at the intervals specified 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
without 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
disappeared, have a Yamaha dealer
replace the brake pads as a set.

Rear brake shoes
The rear brake is provided with a

having to disassemble the brake. To
check the brake shoe wear, check
the position of the wear indicator
while applying the brake. If a brake
shoe has worn to the point that the
wear indicator reaches the wear limit
line, have a Yamaha dealer replace
the brake shoes as a set.

Checking the brake fluid
level
Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low
brake fluid level may indicate worn
brake pads and/or brake system
leakage. If the brake level is low, be
sure to check the brake pads for
wear and the brake system for leak-
age.
1. Mimimum level mark

Observe these precautions:
8When checking the fluid level,
make sure that the top of the
master cylinder is level by turn-
ing the handlebars.
8Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.
8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.8Be careful that water does not
enter the master cylinder when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As 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
suddenly, have a Yamaha dealer
check the cause. Recommended brake fluid:

Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil
seals of the brake master cylinder
and caliper as well as the brake hose
replaced at the intervals listed below
or whenever it is damaged or leaking.
8Oil seals: Replace every two
years.
8Brake hose: Replace every four
years.2. Shift the transmission into the
neutral position.
3. Move the rear wheel by pushing
the motorcycle to locate the tight-
est portion of the drive chain,
and then measure the drive
chain slack as shown.
4. If the drive chain slack is incor-
rect, adjust it as follows.
EAU00744
Drive chain slack
The drive chain slack should be
checked before each ride and adjust-
ed if necessary.
To check the drive chain slack
1. Place the motorcycle on a level
surface and hold it in an upright
position.
NOTE:
When checking and adjusting the
drive chain slack, the motorcycle
should be positioned straight up and
there should be no weight on it.
