WARNING
EWA15541
●
Have a Yamaha dealer replace
excessively worn tires. Operat-
ing the motorcycle with exces-
sively worn tires 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.
●
It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube very carefully and replace it as
soon as possible with a high-
quality product.
●
Ride conservatively after
changing a tire since the tire
must seat itself on the rim prop-
erly. Failure to allow proper
seating may cause tire failure,
which may result in damage to
the motorcycle and injury to the
rider.

The wheel rims should be checked
for cracks, bends, warpage or oth-
