Yamaha Pro X Individual Piston Kits

PROX Yamaha 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 Yamaha WaveRunner Personal Watercraft. PROX Piston Kits for sleeved cylinders are available in standard size and a wide range of oversizes. 

Pro X pistons for Yamaha power valve 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 Pro X Piston Kits are supplied complete with Piston Rings, Wrist Pin and Circlips, ready to install!

Individual piston kits include one piston, rings, clips & wrist pin.
