In recent years, HJC has focused substantial efforts on the development of new technologies and manufacturing capabilities. The outcome of this commitment is impressive: HJC has reinvented the parameters of premium helmet performance with the new advanced-concept HJC RPHA series. The HJC RPHA 10 (formerly the RPS-10) is a high-performance sport/street helmet designed with input from MotoGP star Ben Spies. For riders who prefer a modular design, the HJC RPHA Max brings remarkable lightness, superb aerodynamics and a remarkably quiet interior for true all-day comfort. And the new off-road HJC RPHA X transforms all of this newest technology plus off-road-specific elements into a premier, lightweight dirt bike helmet that`s been race-tested and developed in AMA Pro Supercross and Motocross competition.
