WISECO Forged Piston – Part No. W647M05500
Designed for the Cross environment, this WISECO forged piston is a replacement part intended for engine refurbishment operations and preparations requiring an oversize. Made from aluminum, it features a diameter of Ø 55.00 mm corresponding to an oversize of +1.00 mm (oversize letter: 100) and a "standard" compression height. Ideal for replacing a worn piston after reboring, it fits into the top ends of small-displacement cross bikes.
Recommended use: installation during reboring or cylinder refurbishment. The forged design provides a homogeneous structure and good mechanical strength compatible with the demanding conditions of off-road use, while remaining compliant with the specifications indicated by the manufacturer.
