Upgrade the top end of your KTM 65 with the NAMURA NX-70002-6BK Top End Kit. Designed for Nikasil-plated cylinders with a 44.97 mm piston size, this kit provides the key components needed for a dependable top-end rebuild. It includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit for convenient installation and reliable engine service.
The piston features MOS2, or Teflon and molybdenum, coated skirts. This rolled-on coating process creates a strong bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. The machined smooth head helps reflect combustion heat and reduce carbon buildup, supporting piston protection and consistent engine performance. An anodized dome increases heat resistance and durability, while the hypereutectic casting process adds silicon for controlled expansion, improved wear resistance, and dependable operation at elevated cylinder temperatures.
This NAMURA top end kit is designed to fit 2000–2008 KTM 65 SX models and the 2008 KTM 65 XC. Confirm the cylinder type, model year, and piston specification before installation. Manufacturer part number NX-70002-6BK and vendor part number 185-70026B identify this complete replacement kit for the listed KTM applications.
