Namura Hyperdryve Piston Kit - NA-40025

Namura is proud to bring you the next step in the evolution of powersport pistons. The new Hyperdryve line of pistons was specifically designed as an alternative to the OE for applications that call for the use of forged internals. The major advantage of Hyperdryve pistons is the ability to hold up under temperatures never before seen by cast pistons, without the extra cost of forged equipment.

Hyperdryve pistons are composed of a new hypereutectic aluminum alloy developed for use in the space industry. 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. Hyperdryve is the exclusive line of pistons for 250 and 450CC motocross bikes, as well as select sport quads.
