CHECKING THE TIRES
The following procedure applies to both of the
tires.
1. Check:

tire pressure
Out of specification
Regulate.

The tire pressure should only be checked
and regulated when the tire temperature
equals the ambient air temperature.

The tire pressure and the suspension must
be adjusted according to the total weight
(including cargo, rider, passenger and ac-
cessories) and the anticipated riding
speed.

Operation of an overloaded motorcycle
could cause tire damage, an accident or an
injury.
NEVER OVERLOAD THE MOTORCYCLE.

Do not use a tubeless tire on a wheel de-
signed only for tube tires to avoid tire fail-
ure and personal injury from sudden defla-
tion.

When using a tube tire, be sure to install the
correct tube.

Always replace a new tube tire and a new
tube as a set.

To avoid pinching the tube, make sure the
wheel rim band and tube are centered in the
wheel groove.

Patching a punctured tube is not recom-
mended. If it is absolutely necessary to do
so, use great care and replace the tube as
soon as possible with a good quality re-
placement.

After extensive tests, the tires listed below
have been approved by Yamaha Motor Co.,
Ltd. for this model. The front and rear tires
should always be by the same manufacturer
and of the same design. No guarantee con-
cerning handling characteristics can be giv-
en if a tire combination other than one ap-
proved by Yamaha is used on this
motorcycle.

New tires have a relatively low grip on the
road surface until they have been slightly
worn. Therefore, approximately 100 km
should be traveled at normal speed before
any high-speed riding is done.
For tires with a direction of rotation mark
1:

Install the tire with the mark pointing in the
direction of wheel rotation.

Align the mark
2 with the valve installation
point.
