WÖSSNER Forged Piston - Manufacturer Ref. 8959DB
Designed for motocross and engine maintenance of the 250 cm³ Sherco, this Wössner forged piston offers a robust solution for oversized replacement. Made from aluminum, it maintains the necessary dimensions for boring and restoring the power unit without altering the compression height: standard compression.
- Material: Forged aluminum
- Oversize letter: B
- Bore diameter (mm): 76.01
- Piston diameter: Ø 76.970 mm
- Diameter Ø (mm): 75.97
This piston is intended for engine preparations and repairs following a B oversize boring. The forged construction ensures better heat resistance and cyclic load handling than a conventional cast piston, making it a common choice for cylinders used in off-road conditions.
Main compatibilities: SHERCO 250 SEF-R SIX DAYS (2018), SHERCO 250 SEF-R RACING (2018), SHERCO 250 SEF-R FACTORY (2018). Before installation, check the piston/cylinder clearance and replace rings and pin according to the manufacturer's recommendations to ensure reliable operation.
