Namura Technologies NX-10200K Complete Top End Rebuild Kit Standard Bore 65.47mm

The Namura Technologies NX-10200K is a complete top end rebuild kit designed for Honda 200cc engines at standard bore size (65.47mm). This all-inclusive kit provides everything needed for a full top end overhaul in a single, convenient package — eliminating the hassle and cost of sourcing individual components separately.

Kit Includes:

• Piston
• Piston rings
• Wrist pin
• Wrist pin clips
• Top end bearing
• Complete top end gasket kit

MOS2 (Teflon/Molybdenum) Coated Skirts — Applied via a rolled-on process, the MOS2 coating bonds at a strength 10 times greater than spray-on alternatives. This technology delivers improved heat transfer, reduced piston-to-cylinder friction, and protection against cold seizures during startup.

Machined Smooth Piston Heads — The smoothed head surface reflects combustion heat away from the piston crown and reduces carbon buildup over time. Independent testing has shown this feature can contribute up to a 6% improvement in horsepower and fuel economy.

Anodized Dome — Namura's anodizing process increases both heat resistance and structural durability. Pistons with anodized domes have demonstrated up to 75% greater strength compared to non-anodized pistons.

Hypereutectic Casting Process — The piston is cast using a hypereutectic process that delivers a higher silicon content than standard cast pistons. This results in reduced thermal expansion rates, improved wear resistance, and the ability to withstand elevated cylinder operating temperatures.

The included gasket kit is manufactured to OEM specifications, ensuring proper fitment with no trimming required. Whether restoring compression on a worn engine or performing scheduled maintenance, the NX-10200K delivers OEM-quality reliability at an aftermarket price.
