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.
