PISTON KIT 86-96 CR250 66.40 B, NAMURA NX-10026-B HONDA

Namura Piston Kit - 66.40mm Bore - B

This high-performance Namura piston assembly is engineered in the USA and manufactured in Taiwan. It features a 66.40mm bore size.

Key Features:

• Material: Constructed from high-silicon content hypereutectic cast aluminum for reduced heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing.
• Piston Crown: Machined smooth piston crowns reduce carbon buildup, increasing horsepower and fuel economy. Hard anodized crowns offer 75% greater strength than non-anodized, minimizing expansion and reducing the risk of cold seizures, especially when combined with coated skirts.
• Skirt Coating: MOS2 (Teflon/Molybdenum) coated skirts perform to the highest standards, reducing friction and heat for optimal performance.
• Piston Alloy: Utilizes the same low-expansion, low-friction piston alloy favored by major Japanese engine manufacturers.
• Ring Match: Namura rings are designed to match OEM specifications.
• Oversize Options: Available in fractional oversize pistons (-B:.0004 in. and -C:.0008 in.) for select applications. These can extend cylinder life by renewing original clearance on slightly worn cylinders, potentially avoiding costly sleeve installations.
• Included Components: Piston assemblies include the piston, ring(s), wrist pin, and circlips.
