Accessories & Modifications
Accessories
We strongly recommend that you use only Honda
Genuine Accessories that have been specifically
designed and tested for your CRF. Because
Honda cannot test all other accessories, you must
be personally responsible for proper selection,
installation, and use of non-Honda accessories.
Check with your Honda dealer for assistance and
always follow this guideline:
• Make sure the accessory does not reduce
ground clearance and lean angle, limit
suspension travel or steering travel, alter your
riding position, or interfere with operating any
controls.
Modifications
We strongly advise you not to remove any
original equipment or modify your CRF in any
way that would change its design or operation.
Such changes could seriously impair your CRF’s
handling, stability, and braking, making it unsafe
to ride.
