ProX Piston KitsPiston kits
PROX pistons are precision machined on the latest, state of the art CNC equipment. The same low-expansion, low-friction piston alloy is used as is used for all major Japanese engine manufacturers. PROX Piston Kits are a first class solution to replace the original piston in your Motorcycle, Scooter, Moped, ATV, Personal Watercraft, etc. PROX Piston Kits for sleeved cylinders are available in standard size and a wide range of oversizes. The availability of oversizes up to 2mm significantly helps to increase the lifespan of a cylinder by offering more re-boring possibilities. PROX pistons for plated cylinders come in standard size, as well as in A, B, C, D+ oversizes. Take advantage of the additional oversizes to extend the lifespan of plated cylinders. All PROX Piston Kits are supplied complete with Piston Rings, Wrist Pin and Circlips, ready to install!

ProX valvesValves
PROX Valves are made in Europe to high quality standards. By using a forged one-piece titanium alloy with several integrated material micro structures, specific and different material properties are created in area’s where needed. The high tech Ti3Al alloy has also very good material properties at high temperatures. The special coating creates considerably lower friction between the valve and other parts like valve guides. Therefore the PROX valves exceed OE specifications in dimensions and reliability.
