Tires & Tubes
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.
• Use a replacement tire equivalent to 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.
