Wossner 8066DA Premium Forged 2-Stroke Piston Kit

Refresh your Honda 2-stroke with the Wossner 8066DA Piston Kit, engineered to restore the Factory Quality power and crisp throttle response your CR250R was built for. Specifically designed for the 2002-2004 engine platform, this kit provides the durability and precision required for aggressive motocross and off-road riding. At Moto-House MX, we provide the high-performance components needed to keep your 249cc engine reliable and competitive.

Forged from aerospace-grade aluminum alloy, this piston offers a superior strength-to-weight ratio compared to standard cast alternatives. The permanent skirt coating is a critical feature, significantly reducing friction and piston rock for a quieter engine and improved mechanical efficiency. With optimized machining that balances lightness and structural integrity, the 8066DA is built to withstand the heat and pressure of high-RPM 2-stroke operation.
