Tire Replacement
The tires that came on your CRF were designed to
provide a good combination of handling, braking,
durability, and comfort across a broad range of
riding conditions.
WARNING
Installing improper tires on your
motorcycle can affect handling and
stability. This can cause a crash in which
you can be seriously hurt or killed.
Always use the size and type of tires
recommended in this owner's manual.

• When replacing, use the original equipment
tires or equivalent tires of the same size,
construction, speed rating, and load range as
the original.
• Replace the tube any time you replace a tire.
The old tube will probably be stretched and, if
installed in a new tire, could fail.
