Namura Technologies NX-20065K Top End Repair Kit with Piston, Rings & Gaskets

The Namura Technologies NX-20065K Top End Repair Kit provides everything needed for a complete top end engine rebuild in a single, convenient kit. Engineered for performance and reliability, this kit includes a piston, rings, wrist pin, retaining clips, top end bearing, and a full gasket kit — eliminating the need to source individual components separately.

Key Features:

• MOS2 (Molybdenum/Teflon) Coated Skirts: Applied using a rolled-on process that creates a bond up to 10 times stronger than conventional spray-on coatings. This coating delivers improved heat transfer, reduced friction, and protection against cold seizures during initial startup.
• Machined Smooth Crown: The precision-machined piston crown reflects combustion heat and minimizes carbon deposit buildup, extending piston life. Independent testing has shown this feature may contribute up to a 6% improvement in horsepower and fuel economy.
• Anodized Dome: Anodizing significantly increases heat resistance and structural durability. Pistons with anodized domes are engineered to be up to 75% stronger than non-anodized counterparts, making them ideal for demanding riding conditions.
• Hypereutectic Casting Process: The piston is cast using a hypereutectic process, which results in a higher silicon content. This reduces thermal expansion rates, improves wear resistance, and allows the piston to withstand elevated cylinder temperatures over the long term.
• Complete Kit: Includes piston, piston rings, wrist pin, retaining clips, top end bearing, and gasket set — all components needed for a professional-quality top end rebuild.

Namura Technologies is a trusted name in powersports engine components, delivering OEM-quality fitment with performance-enhancing upgrades. The NX-20065K is a smart choice for riders looking to restore or enhance engine performance with a single, comprehensive solution.
