Periodic maintenance and adjustment
WARNING
 It is dangerous to ride with a
worn-out tire. When a tire tread
begins to show crosswise lines,
have a Yamaha dealer replace
the tire immediately.
 The replacement of all wheel
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience to do so.
 Ride at moderate speeds after
changing a tire since the tire
surface must first be "broken
8
in" for it to develop its optimal
characteristics.
