HJC engineers worked to create a racing helmet truly worthy of the world's top racetracks. The RPHA 1 is the same model used by HJC's world-class athletes, both in MotoGP and WorldSBK, and HJC is ready to finally launch it in full production with FIM homologation (FRHPhe-01) - the safety certification.

Reinforcement materials, including Carbon and Carbon-Glass Hybrid fabric, provide greater impact resistance for a more comfortable and lightweight helmet.
HJC helmets are tested both in the lab and in real life to meet the highest quality standards. HJC is one of very few helmet manufacturers with its own state-of-the-art wind tunnel laboratory to test aerodynamics, ventilation, noise, and more. The HJC wind tunnel test lab measures air forces in a variety of riding conditions to improve helmet performance.
Advanced antibacterial fabric provides improved breathability and quick drying. Removable interior. Eyeglass grooves accommodate riders who wear glasses.
