This kit is designed for select Yamaha 700cc ATV and UTV applications and includes the piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit required for a comprehensive top-end service. The standard-bore piston is engineered for reliable fitment and consistent performance in compatible engines.\u003c\/p\u003e\u003cp\u003eFeaturing MOS2, or Teflon and molybdenum, coated skirts, the piston uses a rolled-on coating process that creates a stronger bond than conventional spray-on applications. The coating helps improve heat transfer, reduce friction, and minimize the risk of cold seizures. Machined-smooth piston heads help reflect combustion heat and reduce carbon buildup, supporting piston protection, performance, and fuel efficiency.\u003c\/p\u003e\u003cp\u003eThe anodized piston dome improves heat resistance and durability, while the hypereutectic casting process provides increased silicon content for controlled expansion, enhanced wear resistance, and reliable operation at higher cylinder temperatures.
