Description
Factory pistons wear down, and a degraded top-end robs your CRF450R of responsiveness and reliability. The Wiseco Piston Kit restores lost compression and throttle response while delivering the durability needed for aggressive trail work or race applications. This is a straightforward bolt-on refresh that pays dividends in power and longevity.
