WÖSSNER Forged Piston – Manufacturer Ref: 8506DA
Designed for the demanding conditions of off-road riding, this Wössner forged piston is a high-precision engine component manufactured in Germany. Intended for the motocross world, it meets the needs of riders looking for an original replacement part or a base for tuning. Its forged aluminum construction and anti-friction treatment on the skirt minimize surface wear and facilitate the break-in process.
This piston is suitable for 2-stroke and 4-stroke engines for which the dimensions correspond (oversize A). Ideal for a rebuild or engine refurbishment, it is particularly suitable for the displacements and models listed by the manufacturer — for example: KTM 400 LC4-E MILITARY (1997, 400 cc). Before installation, check the bore tolerances and adhere to the manufacturer's recommendations for installation and break-in.
