Manufacturer reference: 8186D100

WÖSSNER forged piston specifically designed for motocross use. Made in Germany, this forged aluminum piston meets the robustness standards required on the tracks: skirt treated with anti-friction to limit wear and play, machined tolerances for a smooth operation with the bore.

• Type: forged piston
• Material: aluminum
• Piston diameter: Ø 48.95 mm (bore 49.00 mm)
• Oversize: letter 100 (size +0.10 mm)
• Compression: standard
• Delivered with rings, circlips, and pin

This piston is suitable for 2-stroke engines prepared for motocross where resistance to thermal and mechanical shocks is crucial. The precise machining and treatment of the skirt facilitate the break-in process and contribute to a good piston-cylinder seal from the first revolutions. Supplied complete with ring(s), circlips, and pin, it allows for a clean and quick replacement during an engine overhaul.

Compatible with several historical models such as YAMAHA YZ 80 (1985-1987). Always check the bore diameter and reference before installation to ensure proper compatibility with your engine.
