ProX
Piston Kits
ProX Piston 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. ProX piston kits for sleeved cylinders are available in standard size and a wide range of over sizes. ProX pistons for plated cylinders come in standard size, A, B, C, D & over sizes. All ProX piston kits are supplied complete with piston rings, wrist pin and circlips, ready to install!
