Namura Forged Piston Kit for 2003-14 Yamaha WR450F - 94.95mm - FX-40045-B

Namura Forged Piston Kit for 2003-14 Yamaha WR450F - 94.95mm - FX-40045-B

Namura Forged Piston Kit

  • Namura Forged pistons offer dyno-proven gains in performance and durability over industry-standard 4032 forged pistons.
  • Namura's exclusive forged alloy offers lower expansion rates, allowing for tighter build tolerances and superior tensile and yield strength at operating temperatures.
  • Hard anodized domes for reduced carbon build-up and heat resistance and M0S2 coated skirts for excellent break-in protection and properties.
  • 100% CNC-machine piston domes.

Namura offers direct replacements for the original equipment as well as hi-compression and a variety of bore sizes to meet your ride's needs. MOS2 (Teflon/Molybdenum) Coated Skirts increased heat transfer, reduced friction, and helping to eliminate cold seizures. Machined Smooth Heads Reflect combustion heat and reduces carbon buildup, protecting the top of the piston. Anodized Domes Increase heat resistance and durability; anodized domes are 75% stronger than non-anodized pistons. Namura gives you a higher performance piston without the higher price. Namura piston kits come with the piston individually wrapped, a set of high quality rings packed in their own box, a wrist pin, and circlips.
