9 Owners are personally responsible for their vehicle’s condition. Your motorcycle’s vital functions can start to
deteriorate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements).
Any damage, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very important
that, in addition to a thorough visual inspection, you check the following points before each ride.

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.
EAU00685
Wheels
To ensure maximum performance,
long service, and safe operation,
note the following:
8Always inspect the wheels
before a ride. Check for cracks,
bends or warpage of the
wheel. Be sure the spokes are
tight and undamaged. If any
abnormal condition exists in a
wheel, consult a Yamaha deal-
er. Do not attempt even small
repairs to the wheel. If a wheel
is deformed or cracked, it must
be replaced.
8Tires and wheels should be
balanced whenever either one
is changed or replaced. Failure
to have a wheel balanced can
result in poor performance,
adverse handling characteris-
tics, and shortened tire life.8Ride at moderate speeds after
changing a tire since the tire
surface must first be broken in
for it to develop its optimal
characteristics.
