NAMURA PISTON KIT NX-70029 SIZE A BORE 54.00mm. High-performance Namura pistons are engineered in the USA and manufactured in Taiwan. Constructed from high-silicon content Hypereutectic cast aluminum material for reduced 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 perform at the highest standards, reducing friction and heat for added power and longevity. Namura rings match OEM design except as noted. Fractional oversize pistons are available for some applications to extend the life of your cylinder by renewing original clearance, avoiding expensive sleeve installation. Piston assemblies include ring(s), wrist pin, and circlips. Part No. 56-W010.A.NT.

FULL DESCRIPTION

Namura Piston Kit NX-70029 Size A 54.00mm

This high-performance Namura Piston Kit is engineered in the USA and manufactured in Taiwan. It is designed to meet the demanding needs of motorcycle engines, offering enhanced durability and performance.

Key Features:

  • Material: Constructed from high-silicon content Hypereutectic cast aluminum for reduced heat expansion, tighter clearances, increased hardness, and longer life with reduced scuffing.
  • Piston Crown: Features a machined, smooth piston crown design to minimize carbon buildup, leading to increased horsepower and improved fuel economy.
  • Hard Anodized Crown: The hard anodized crown is 75% stronger than non-anodized versions, providing minimal expansion and reducing the risk of cold seizures. This is further enhanced by the Teflon/Molybdenum coated skirts.
  • MOS2 Coated Skirts: The MOS2 (Teflon/Molybdenum) coated skirts offer superior performance by reducing friction and heat, contributing to added power and longevity.
