WARNING
Have a Yamaha dealer replace

excessively worn tires. Besides
being illegal, operating the mo-
6-21
torcycle with excessively worn
tires decreases riding stability
and can lead to loss of control.
The replacement of all wheel-

EWA10461
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
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 optimal
characteristics.
