HJC RPHA 1 Red Bull Austin GP Helmet

The RPHA 1 was designed and developed after several years of concentrated effort and crucial feedback from world-class athletes in MotoGP. HJC's top engineers got to work and created a race-ready helmet that is truly worthy of the top circuits around the world. The RPHA 1 is the same model used by HJC's world-class athletes in both MotoGP and WorldSBK, and HJC is ready to finally put it into production with FIM homologation (FRHPhe-01) - safety certification.
