Rebuilding a 4 St. top-end with a Namura piston kit for your 2013-2016 Honda CRF450R can help restore the performance of your 450cc engine.

The new Hyperdryve line of 4 stroke pistons from Namura is composed of a hypereutectic aluminum alloy that maintains its high tensile strength up to 700°F, 50% higher than a conventional cast piston. Hyperdryve pistons can hold up under operating conditions normally reserved for forged pistons without the extra cost of forged equipment. They are an exclusive line of pistons for 250cc and 450cc 4 Stroke motocross bikes, as well as selected sport quads. Testing shows the new aluminum alloy is able to maintain a higher strength for longer periods of time compared to conventional aluminum alloy pistons.

Namura piston kits come with the piston, rings, and wrist pin, and top end gasket kit - All in one Box

Features:

  • High-silicon content hypereutectic cast aluminum material is utilized in the Namura 4 Stroke Piston for its advantages such as less heat expansion, tighter clearances, increased hardness, longer life and reduced scuffing.
  • Namura's 4 Stroke Piston includes machined and polished piston crowns to combat carbon buildup which results in increased horsepower and fuel economy.
  • Hard anodized crowns, having a 75% increase in strength over non-anodized crowns, have minimal expansion and also decrease the risk of cold seizures, when used in conjunction 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 piston rings match the OEM design except as noted
  • Namura 4 Stroke Pistons are a great option with some applications that can extend the life of your expensive cylinder. They come in two fractional oversize options, -B (.0004 in.) and -C (.0008 in.), and have the ability to renew the original clearance of your cylinder if it's slightly worn, which can help avoid the need for an expensive sleeve installation.
