Wossner 8022DA Piston Kit - 1989-1998 Suzuki RM250 RMX250 2-Stroke Motocross

Wossner 8021DA Premium Forged 2-Stroke Piston Kit

Give your Suzuki 2-stroke the top-end refresh it deserves with the Wossner 8021DA Piston Kit. Designed to restore Factory Quality compression and that signature crisp throttle response, this kit is engineered for the high-performance demands of the RM250 and RMX250 platforms. Whether you are racing vintage motocross or hitting technical off-road trails, Moto-House MX provides the precision-forged components required to keep your engine running at its absolute peak.

Forged from aerospace-grade aluminum alloy, this piston offers superior strength and heat resistance compared to standard cast alternatives. The 8021DA features a permanent skirt coating that significantly reduces internal friction and piston rock, resulting in a quieter engine and improved mechanical efficiency. Optimized machining ensures the piston remains lightweight for fast revving while maintaining maximum structural integrity in high-stress areas like the crown and skirt walls.
