PERIODIC MAINTENANCE AND ADJUSTMENT
NOTICE
 Be sure the bead stoppers are
tightened. Loose bead stoppers
will cause the tire to slip off the
rim if tire pressure is too low.
 Be sure the valve stem is posi-
tioned straight. A tilted valve
stem indicates that the tire has
slipped from its original position
on the rim. Rotate the tire so
that the valve stem is positioned
straight.
If the center tread depth reaches the
2
specified limit, if the tire has a nail or
glass fragments in it, or if the sidewall
is cracked, have a Yamaha dealer re-
place the tire immediately.

Minimum tire tread depth (front and
rear):
4.0 mm (0.16 in)
Tire information
This model is equipped with tube tires.
Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
ECA15581
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
The front and rear tires should be of
the same make and design, other-
wise the handling characteristics of
the vehicle may be different, which
could lead to an accident.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha.
