Namura Technologies NX-20025-2 Piston Kit Hypereutectic Coated - 66.90mm MOS2

The Namura Technologies NX-20025-2 is a high-performance piston kit featuring a 66.90mm bore size, designed for superior durability and performance in powersports applications. This premium piston kit incorporates advanced materials and manufacturing techniques to deliver enhanced reliability and power output.

Advanced Coating and Surface Treatments:

• MOS2 Coated Skirts: Features a rolled-on Teflon/Molybdenum coating that bonds 10 times stronger than spray-on alternatives, providing increased heat transfer, reduced friction, and protection against cold seizures
• Machined Smooth Heads: Precision-machined piston crown reflects combustion heat and minimizes carbon buildup, potentially increasing horsepower and fuel economy by up to 6%
• Anodized Domes: Hard anodized treatment increases heat resistance and structural integrity, making the piston 75% stronger than non-anodized designs

Construction and Materials:

• Hypereutectic casting process with higher silicon content for reduced thermal expansion and improved wear resistance
• Enhanced ability to withstand elevated cylinder temperatures
• Precision-engineered for optimal performance and longevity

This complete piston kit includes the piston, rings, wrist pin, and circlips, providing everything needed for a professional rebuild. Namura Technologies pistons are manufactured to OEM specifications or better, making them an excellent choice for both replacement and performance applications.
