This complete kit includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit for a convenient engine rebuild solution. The kit is intended for use with the original Nikasil-plated cylinder and is engineered to provide dependable fit and function when servicing a worn or damaged top end.\u003c\/p\u003e\u003cp\u003eThe Namura piston uses a hypereutectic casting process that increases silicon content to help reduce expansion, improve wear resistance, and withstand elevated cylinder temperatures. Its MOS2, or Teflon\/molybdenum, coated skirts use a rolled-on application process designed to create a stronger bond than conventional spray-on coatings. This coating helps reduce friction, improve heat transfer, and minimize the risk of cold seizures during operation.\u003c\/p\u003e\u003cp\u003eAdditional piston features include machined-smooth heads to reflect combustion heat and help limit carbon buildup, along with anodized domes for improved heat resistance and durability. These design features support consistent combustion performance and long-term component protection. The included gasket kit, bearing, rings, wrist pin, and clips help provide the essential components needed for a comprehensive top-end service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Fits 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, and 2012 KTM 85 SX 17\/14 models.
