Manufacturer reference: 8109DA — WÖSSNER forged piston, designed for motocross use. Manufactured in Germany by specialists in engine parts for 2 and 4-stroke engines, this piston is aimed at riders looking for a robust component suitable for off-road conditions.

• High-quality forged aluminium piston
• Piston diameter: Ø 67.340 mm (nominal bore 67.40 mm) — Oversize letter: A
• Number of rings: 2 — supplied with rings, circlips, and pin
• Anti-friction treatment of the skirt to limit hot spots and wear

The Wössner piston is installed as a replacement component in engine preparations and revisions for the 250 cm3 displacements mentioned in compatibility. Its forged construction provides a dense structure suitable for the demands of motocross: sharp accelerations, high revs, and frequent load changes. The skirt treatment reduces adhesion and contributes to better sliding in the cylinder during the engine's hot phases.

Compatibility (examples): KAWASAKI KDX 250 (KDX250D/E) and KAWASAKI KX 250 (KX250H). Before installation, check the bore size and engine tolerances to confirm the use of oversize A. Supplied complete for piston/pin assembly: rings, circlips, and pin included.
