The PROX forged piston (ref. 01.6608.A) is designed for riders looking for a serious engine reconditioning on 690 cm3 engines. Machined from a specific aluminum alloy and forged for a denser grain structure, it aims to reduce internal friction and provide increased resistance to thermomechanical stresses encountered in road or off-road use.
This piston is suitable for installation during a re-bore with oversize A. Its machining and tolerances are designed for precise fitting in the cylinder, facilitating break-in and limiting premature wear. Ideal for interventions on roadster and motocross engines from the 690 family.
