WARNING
EWA10530
Proper loading of your motorcycle is
important for several characteristics
of your motorcycle; such as han-
dling, braking, performance and
safety. Do not carry loosely packed
items that can shift. Securely pack
your heaviest items close to the cen-
ter of the motorcycle, and distribute
the weight evenly from side to side.
Check the condition and pressure of
your tires. NEVER OVERLOAD
YOUR MOTORCYCLE. Make surethe total weight of the cargo, rider,
passenger, and accessories (fairing,
saddlebags, etc. if approved for this
model) does not exceed the maxi-
mum load of the motorcycle. Opera-
tion of an overloaded motorcycle
could cause tire damage, an acci-
dent, or even injury.
Tire inspection
The tires must be checked before each
ride. If the tire shows crosswise lines
(minimum tread depth), if the tire has a
nail or glass fragments in it, or if the
sidewall is cracked, have a Yamaha
dealer replace the tire immediately.
NOTE:
The tire tread depth limits may differ
from country to country. Always complywith the local regulations.
Tire information
This motorcycle is equipped with tube
tires.
WARNING

WARNING
EWA10560
It is dangerous to ride with a
worn-out tire. When a tire tread
begins to show crosswise lines,
have a Yamaha dealer replace
the tire immediately.
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.
It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube very carefully and replace it as
soon as possible with a high-
quality product.
EAU21940
Spoke wheels To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points
regarding the specified wheels.
The wheel rims should be checked
for cracks, bends or warpage, and
the spokes for looseness or dam-
age before each ride. If any dam-
age 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 han-
dling characteristics, and a short-
ened tire life.
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be
“broken in ” for it
to develop its optimal characteris-
tics.

Checking 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
EWA14210
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 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 acci-dent.
EAU22181
Adjusting the brake pedal free
play The brake pedal free play should mea-
sure 25.0–35.0 mm (0.98–1.38 in) at
the brake pedal end as shown. Period-
ically check the brake pedal free play
and, if necessary, adjust it as follows.
To increase the brake pedal free play,
turn the adjusting nut in direction (a). To
decrease the brake pedal free play,
turn the adjusting nut in direction (b).

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 main-
tenance and lubrication chart.
EAU22430
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 wearindicator grooves have almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
EAU22540
Rear brake shoes
The rear brake is provided with a wear
indicator, which allows you to check the
brake shoe wear without having to dis-
assemble the brake. To check the

Checking the front brake fluid
level Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing 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 fluid level is low, be sure to check
the brake pads for wear and the brake
system for leakage.
Observe these precautions:
When checking the fluid level,
make sure that the top of the mas-
ter cylinder is level by turning the
handlebars.
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
NOTE:If DOT 4 is not available, DOT 3 can beused.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
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 grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
