Description

Whether you're rebuilding a tired CRF450R or preparing for peak performance, the Wiseco 96mm piston delivers the compression ratio and material science you need to extract maximum horsepower and reliability from your engine. Factory pistons wear, lose clearance, and compromise combustion efficiency—this high-silicon aluminum forging restores top-end power while handling the extreme temperatures of sustained racing. The 12.5:1 compression ratio is engineered specifically for the 449cc displacement, giving you the torque curve and throttle response that separates competitive riders from the rest.
