It is engineered to support reliable fitment and dependable performance when restoring the upper end of the engine.\u003c\/p\u003e\u003cp\u003eThe piston features MOS2, or Teflon and molybdenum, coated skirts applied through a rolled-on process for a durable bond. This coating helps improve heat transfer, reduce friction, and minimize the risk of cold seizures. The machined smooth head helps reflect combustion heat and reduce carbon buildup, while the anodized dome is designed to improve heat resistance and piston durability. Namura’s hypereutectic casting process provides increased silicon content for reduced expansion, added wear resistance, and improved tolerance of elevated cylinder temperatures.\u003c\/p\u003e\u003cp\u003eManufacturer part number NX-70005K is listed for the following applications: 2009–2017 KTM 65 SX and 2009 KTM 65 XC.
