NOTE:
Pre-operation checks should be made each time the motorcycle is used. Such an inspection
can be thoroughly accomplished in a very short time; and the added safety it assures is
more than worth the time involved.wIf any item in the Pre-Operation Check is not working properly, have it inspected and re-
paired before operating the motorcycle.

2. Tire inspection
Always check the tires before operat-
ing the motorcycle. If center tread
depth reaches the limit as shown, if
the tire has a nail or glass fragments
in it, or if the side wall is cracked, con-
tact a Yamaha dealer immediately and
have the tire replaced.wIt is dangerous to ride with a worn-out
tire. When a tire tread begins to show
lines, have a Yamaha dealer replace the
tire immediately. Brakes, tires, and related
wheel parts replacement should be left to
a Yamaha Service Technician.
