HJC RPHA 1N Brad Binder Adult Street Helmets
The RPHA 1N Brad Binder helmet, developed with input from MotoGP athletes, is HJC’s race-bred model used in MotoGP and WorldSBK. FIM-certified with advanced aerodynamics, top-tier ventilation, and premium materials, it's built for elite performance on the track.
The RPHA 1N was designed and developed after several years of focused efforts and crucial feedback from top world-class athletes in MotoGP. HJC’s top engineers went to work and created a race-bred helmet that is truly worthy of top race circuits around the world. The RPHA 1N is the very same model used by HJC’s world-class athletes in both MotoGP and WorldSBK.
