Cast wheelsTo maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
 The wheel rims should be
checked for cracks, bends, warp-
age or other damage 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 de-
formed or cracked wheel must be
replaced.
 The front wheels should be bal-
anced whenever either the tires or
wheels have been changed or re-
placed. An unbalanced wheel can
result in poor performance, ad-
verse handling characteristics,
and a shortened tire life.
