●Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
vehicle with excessively worn
tires decreases riding stability
and can lead to loss of control.
●The replacement of all wheel
and brake related parts, inclu-
ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience.

Cast wheels
To maximize the performance, durabi-
lity, and safe operation of your vehi-
cle, note the following points regar-
ding the specified wheels.
●The wheel rims should be chec-
ked for cracks, bends or warpage
before each ride. If any damage
is found, have a Yamaha dealer
replace the wheel. Do not
attempt even the smallest repair
to the wheel. A deformed or crac-
ked wheel must be replaced.
●The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced.
An unbalanced wheel can result
in poor performance, adverse
handling characteristics, and a
shortened tire life.
●Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for
it to develop its optimal characte-
ristics.
