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 replace the tire imme-
diately.

The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.

w8Have a Yamaha dealer replace
excessively worn tires.
Besides being illegal, operat-
ing the motorcycle with exces-
sively worn tires decreases
riding stability and can lead to
loss of control.
8The replacement of all wheel-
and brake-related parts,
including the tires, should be
left to a Yamaha dealer, who
has the necessary profession-
al knowledge and experience.
8It is not recommended to
patch a punctured tube. If
unavoidable, however, patch
the tube very carefully and
replace it as soon as possible
with a high-quality product.
Tire information
