Designed for KTM 65 two-stroke engines with Nikasil-plated cylinders, this kit includes the piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit needed for a comprehensive top-end service. The 44.97 mm piston is engineered for the specified cylinder application and provides a reliable replacement solution for worn or damaged components.\u003c\/p\u003e\u003cp\u003eThe Namura piston features MOS2, or Teflon and molybdenum, coated skirts applied through a rolled-on process. This coating is designed to provide a strong bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. Machined smooth heads help reflect combustion heat and reduce carbon buildup, supporting piston protection and consistent engine operation. The anodized dome improves heat resistance and durability, while the hypereutectic casting process increases silicon content for controlled expansion, added wear resistance, and improved performance under elevated cylinder temperatures.\u003c\/p\u003e\u003cp\u003eThis Namura Top End Kit fits 2009 through 2017 KTM 65 SX models and the 2009 KTM 65 XC.
