WÖSSNER Pro Series Forged Piston — Ref. 8894DA

Designed for the motocross world, this Wössner forged piston meets the demands of 2-stroke and 4-stroke engines. Precision machined in Germany, it is intended for builds and replacements requiring tight tolerances and reliable mechanical performance. The skirt features an anti-friction treatment to reduce hot friction and improve behavior at high RPMs.

• Recommended bore diameter: 77.00 mm
• Piston diameter: Ø 76.950 mm (oversize A)
• Material: forged aluminum
• Number of rings: 2
• Complete kit: rings, circlips, and pin

The oversize A diameter allows for compensation of slight reboring of the cylinder. This piston is suitable for refurbishment work and engines subjected to high RPMs on track or rough terrain. Its forged design promotes homogeneity and resistance to thermomechanical loads superior to that of a cast piston, while not promising unverified gains in power.

Common compatibilities: Yamaha WR 250 F (RE25/CG36) and YZ 250 F (CG34) — models 2015–2017 (250 cm³). Always check the fit and piston/cylinder clearances before installation.
