PISTON KIT 01-20 KTM125 SX 54, NAMURA NX-70029, 2-RING

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.
• Ring Design: Namura rings are designed to match OEM specifications unless otherwise noted.
• Oversize Options: Fractional oversize pistons, such as -B (.0004 in.) and -C (.0008 in.), are available for specific applications. These extend the life of the cylinder by renewing the original clearance if slightly worn, avoiding costly sleeve installations.
• Included Components: Piston assemblies come complete with ring(s), wrist pin, and circlips.
