Tyres & Tubes
The tyres 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 tyre equivalent to the
original.
• Replace the tube any time you replace a tyre.
The old tube will probably be stretched and, if
installed in a new tyre, could fail.
