have a Yamaha dealer replace

To 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, warpage or
damage before each ride. If any
damage is found, have a Yamaha
dealer replace the wheel. Do not
EWA10580
attempt even the smallest repair to
the wheel. A deformed or cracked
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 han-
dling characteristics, and a short-
ened 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 characteris-
tics.
• After repairing or replacing the rear
tire, tighten the valve stem nut and
locknut to the specified torques.
