The same low-expansion, low-friction piston alloy is used as is used by all major Japanese engine manufacturers. The Prox Piston Kit is a first-class solution for replacing the original piston in your motorcycle, scooter, moped, ATV, personal watercraft, etc. ### Advanced Coating for Ultimate Performance Most Prox pistons come with a special coating. The tin coating assists the break-in process when you first start the bike. A modern skirt coating not only assists the break-in process but also helps reduce friction after break-in is complete. The black coating, made from a precisely selected mix of materials, further increases engine performance. ### Availability for Various Cylinder Types Prox pistons are available for Nikasil-plated and sleeved cylinders. They are offered in standard size, as well as in A, B, C, and D+ oversizes, allowing for a perfect fit for your engine. The wide range of available oversizes (up to 2mm) significantly extends the cylinder's lifespan by offering more re-boring possibilities. ### Complete Kit, Ready to Install The Prox 01.4251 piston kit (from 53.54mm to 53.96mm) includes piston rings, a wrist pin, and circlips, allowing for immediate installation.
