WÖSSNER Forged Piston – Manufacturer Ref: 8630DA
Forged piston specially developed for motocross, manufactured in Germany by Wössner. Machined from aluminum, this oversized A piston features a skirt finish treated for anti-friction and a geometry suited for the high demands of 4T engines of 450 cm³. Supplied complete with its rings, circlips, and pin, it allows for precise restoration after reboring.
Designed for off-road motorcycles, this piston is intended for rebuilds after reboring where an oversize A is required. It is particularly suitable for 450 cm³ models such as YAMAHA WR 450 F (DJ03) 2015, GAS GAS EC 450 F 2015, and YAMAHA WR 450 F (CJ13) 2011. Before installation, check compatibility with your bore, cylindrical condition, and manufacturer specifications.
Recommended use: motocross / off-road. German-made Wössner — engine component intended for replacement and engine overhaul.
