8Operating the motorcycle with
excessively worn tires
decrease riding stability and
can lead to loss of control.
Have excessively worn tires
replaced by a Yamaha dealer
immediately. Brakes, tires, and
related wheel parts replace-
ment should be left to a
Yamaha Service Technician.
8Patching a punctured tube is
not recommended. If it is
absolutely necessary to do so,
use great care and replace the
tube as soon as possible with
a good quality replacement.
