2013 Honda CRF450R

Honda's CRF450R has remained one of the most popular full size bikes since its introduction. In 2013, Honda yet again made some drastic chassis modifications. This revised model comes with 48mm KYB forks and 50mm KYB Shock instead of the traditional Showa suspension of previous years. The change in suspension manufacturers seems to have led to a similar downfall as the prior CRF450R models with inadequate damping and spring rates.

The correct spring rate, specified for the rider’s weight, and customized valving tuned for application and skill level is required for a proper setup on the CRF450R. Correct spring rates and Race Tech Gold Valves will increase bottoming resistance and plushness over braking bumps, as well as square edged chop.
