Features
WÖSSNER Forged Piston - Manufacturer Ref. 8553D500
Designed and manufactured in Germany by Wössner, this forged piston is aimed at motorcyclists who value high-quality engine parts. Intended for the Roadster segment and compatible with both 2-stroke and 4-stroke engines, it features a forged aluminum construction and a skirt that benefits from an anti-friction treatment to minimize friction against the cylinder wall.
- Bore diameter: 65.00 mm
- Piston diameter: Ø 64.95 mm (Ø 64.950 mm)
- Oversize: letter 500 → +0.50 mm
- Compression: standard
- Delivered complete: ring(s), circlips, and pin
The Wössner piston is presented as a precision-machined replacement part, suitable for engine refurbishment operations or rebuilds where the piston and its assembly components are replaced. The bore and piston values correspond to the specified tolerances to ensure a proper piston-cylinder clearance.
Useful reference for owners of small displacements: possible fitment on models such as the YAMAHA XT 125 (1986 - 125 cm3). Always check the exact compatibility with your engine before installation.
