Wossner 76.97mm Piston Kit for Suzuki RM-Z250 2010-2019 8781DB

If you're running a RM-Z250 and expecting reliable power delivery through every race, a quality piston kit isn't negotiable. Worn or stock pistons compromise combustion efficiency, increase friction losses, and shorten engine life—especially in 2-stroke applications where tolerances are critical. The Wossner 8781DB delivers the precision engineering and durability you need to maintain consistent performance lap after lap.

This complete kit includes everything required for installation: piston, rings, wrist pin, and clips. The 4032 T6 forged aluminum construction provides the strength-to-weight ratio essential for high-RPM 2-stroke engines, while Wossner's proprietary skirt coating reduces friction and piston rock, resulting in quieter operation and improved reliability. The T6 heat-treatment process enhances thermal resistance, making this kit suited for sustained high-load conditions typical of competitive riding.
