PROX Forged Piston specially designed for Cross practice. Forged from a specific aluminium alloy, this piston offers a robust design suited to the severe constraints of supercharged cylinders at high revs and the demands of off-road riding. Its finish reduces internal friction and facilitates precise guidance in the bore for a smooth engine response.
Designed for Cross motorcycles, this forged piston is aimed at riders looking for a reliable replacement part to rebuild an engine or perform a preparation: reinforced skirt, controlled tolerances, and compatibility with a complete segment kit. It is suitable, among others, for KAWASAKI KX 450 F models from the years 2014, 2017, and 2018 (KX450F / KX450H).
Before installation, check the bore and adhere to the manufacturer's clearances during installation. For any specific preparation, coordinate with your preparer or workshop to ensure compliance and engine longevity.
