2. Tire wear indicator
3. Tire tread depth
Always check the tires before operating
the motorcycle. If a tire tread shows
crosswise lines (minimum tread depth),
if the tire has a nail or glass fragments
in it, or if the sidewall is cracked, con-
tact a Yamaha dealer immediately and
have the tire replaced.

excessively worn tires. Besides
being illegal, operating the vehi-

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.

rear):

TIP
The tire tread depth limits may differ
from country to country. Always comply

WARNING
The front and rear tires should
be of the same make and de-

cycle may be different, which
could lead to an accident.
Always make sure that the valve

prevent air pressure leakage.
