WÖSSNER Forged Piston – Manufacturer Ref: 8520DB
Designed and manufactured in Germany by Wössner, this forged piston is aimed at riders who are demanding about maintenance and rebuilding cross engines. Intended for 2-stroke and 4-stroke applications, it features the precise dimensions required for KTM 600 engine models (years 1991-1992) and other compatible blocks with a diameter of Ø 94.95 mm.
- Type: forged aluminum piston
- Piston diameter: Ø 94.95 mm (oversize letter B)
- Recommended bore diameter: 95.01 mm
- Compression: Standard
- Anti-friction treated skirt to minimize friction
- Delivered complete with ring(s), circlips, and piston pin
This piston features factory dimensions in oversize B, suitable for a bore regrind corresponding to the indicated diameter. The skirt finish reduces wear and facilitates break-in, while German machining and quality control ensure a part that meets professional tolerances. Ideal for engine revision or replacement during specific preparation, it integrates into cross setups where bore precision and reliable assembly are essential.
Common compatibilities: KTM 600 MX (1991-1992), KTM 600 GS (1992) — always check the engine number and dimensions before installation.
