Our OEM style Tin coated pistons assist the wear in process when you just started the bike. We have developed a new skirt coating that not only assists the wear-in process but also helps reduce friction after the wear-in. The black coating is made from a delicate mix of materials and will increase performance. The latest cylinders are plated by Nicasil plating.
