9 Tire 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 sidewall is
cracked, have a Yamaha dealer re-
place the tire immediately.
TIPThe 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
EWA10461
The front and rear tires should be of
the same make and design, other-
wise the handling characteristics of
the vehicle may be different, whichcould lead to an accident.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha Motor Co., Ltd.
WARNING
EWA10571

Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the mo-torcycle with excessively worn
tires decreases riding stability
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.

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.

Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken
in” for it to develop its optimalcharacteristics.

Checking the shift pedal The operation of the shift pedal should
be checked before each ride. If opera-
tion is not smooth, have a Yamaha
dealer check the vehicle.

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.
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 wear
indicator grooves have almost disap-peared, have a Yamaha dealer replace
the brake pads as a set.

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

pad has worn to the point that the wear
indicator groove almost appears, have
a Yamaha dealer replace the brake
pads as a set.
