tires, should be left to a Yamaha
dealer, who has the necessary
professional knowledge and ex-

EAU21960
Cast wheelsTo maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points regard-
ing the specified wheels.●
The wheel rims should be checked
for cracks, bends or warpage be-
fore each ride. If any damage is
found, have a Yamaha dealer re-
place the wheel. Do not 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. Wheels
