Overview of Namura Hyperdryve Piston Assembly - 76.95mm Bore - NX-20031
  • The new HYPERDRYVE line of pistons is composed of a space-age hypereutectic aluminum alloy developed by NASA.
  • Engineered to maintain its high tensile strength up to 700° F(370°C), 50% higher than a conventional cast piston, this gives HYPERDRYVE the strength to perform under operating conditions normally reserved for forged pistons.
  • This revolutionary alloy, combined with our already existing features of machined smooth anodized heads (for better heat reflection) and MOS2 coated skirts (giving you smoother startups and break ins) meets the demands of todays 4-stroke engines.
  • HYPERDRYVE is the exclusive line of pistons for 250 and 450CC motocross bikes, as well as select sport quads.
  • Piston assemblies include ring(s), wrist pin and circlip
  • Forged; compression 13.5:1
