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!

ProX 2-Stroke Piston Kits
• ProX pistons are manufactured by the same factories in Japan that supply the OEMs. This ensures OEM quality but allows ProX to make improvements upon OEM designs when needed. • The majority of ProX 2-stroke pistons are cast from aluminum containing approximately 18% silicon. This material and manufacturing combination reduces thermal expansion, allowing pistons to be run at tighter tolerances and reducing wear. • ProX adds additional performance features to piston designs where they feel necessary. For example, some 2-stroke pistons will have wrist pin oiling holes drilled in the bottom of the pin towers. • A quality piston’s performance is only as good as the components it uses. ProX 2-stroke pistons come with OEM quality, Japanese rings to ensure durabilty and performance is consistent throughout the entire piston package.
