WOSSNER Forged Piston – Manufacturer Ref.: 8194D200

Wössner forged piston, made in Germany by a specialist in engine parts for 2 and 4 strokes. Designed for off-road and motocross use, this aluminum piston features a friction-reducing treatment on the skirt to limit wear and tear under the demanding conditions of the track.

• Bore diameter: 69.00 mm
• Piston diameter: Ø 68.94 mm (letter oversize 200 → +0.20 mm)
• Compression: standard
• Material: forged aluminum
• Delivered complete: ring(s), circlips, and pin

The forged manufacturing process provides a more homogeneous metal structure and superior resistance to thermal and mechanical shocks compared to cast pistons, a valuable asset for demanding motocross engines. The skirt treatment reduces seizing and facilitates the break-in process, while the +0.20 mm oversize allows for precise fitting to a honed bore.

Replacement part suitable for the listed historical 250 cc models (e.g., SUZUKI RM 250 — 1979/1980/1981). Check the diameter and engine reference before installation to ensure compatibility and a piston/cylinder clearance that meets manufacturer specifications.
