Namura Piston Kit NX-10026. 66.40mm bore. For 1986-1996 Honda CR250R. Engineered in the USA, manufactured in Taiwan from high-silicon content Hypereutectic cast aluminum material for less heat expansion, tighter clearances, increased hardness, longer life and reduced scuffing. Features machined, smooth piston crowns for reduced carbon buildup, increased horsepower and fuel economy. Hard anodized crowns are 75% stronger than non-anodized, providing minimal expansion and reducing the chance of cold seizures when combined with Teflon/Molybdenum coated skirts. MOS2 (Teflon/Molybdenum) coated skirts reduce friction and heat. This piston alloy is used by major Japanese engine manufacturers. Piston assemblies include ring(s), wrist pin and circlips. Namura rings match OEM design. Oversize pistons are available for some applications to extend cylinder life.

FULL DESCRIPTION
Namura Piston Assembly
This high-performance piston assembly is engineered in the USA and manufactured in Taiwan. It is constructed from a high-silicon content, hypereutectic cast aluminum material designed for reduced heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing.
Key Features:
- Machined Piston Crowns: Smooth piston crowns reduce carbon buildup, enhancing horsepower and fuel economy.
- Hard Anodized Crowns: Offers 75% greater strength than non-anodized crowns, minimizing expansion and reducing the risk of cold seizures when combined with Teflon/Molybdenum coated skirts.
- MOS2 (Teflon/Molybdenum) Coated Skirts: Engineered for superior performance by reducing friction and heat.
- Durable Piston Alloy: Utilizes the same low-expansion, low-friction piston alloy favored by major Japanese engine manufacturers.
- Complete Piston Kits: Assemblies include the piston, ring(s), wrist pin, and circlips.
- Oversize Options: Available in fractional oversize options to extend cylinder life by restoring original clearance, potentially avoiding costly sleeve installations.
- Ring Design: Namura rings are designed to match OEM specifications.
