Rear tire (XT660X)

WARNING

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.

NOTE:

For tires with a direction of rotation mark

• Install the tire with the mark pointing in the

direction of wheel rotation.

• Align the mark

with the valve installation

point.
