HJC RPHA 31 BLACK SML - RPHA 31

The HJC RPHA 31 Helmet is built for riders who want premium open-face comfort with refined aerodynamic performance. Its PIM Evo shell construction combines advanced materials with multi-density EPS to create a lightweight helmet focused on impact management and long-distance comfort. Developed through extensive wind tunnel testing, the RPHA 31 is engineered to reduce wind turbulence and maintain a smoother, quieter ride at speed. The advanced ventilation system channels airflow efficiently through the helmet to help manage heat and humidity, while the distortion-free HJ-39 shield delivers a wide, clear field of view. An adjustable 3-step integrated sun shield helps adapt to changing light conditions, and the improved 2-way pivot ratchet system enhances shield sealing and movement. Designed for modern riders, the RPHA 31 also features eyeglass-friendly cheek pads and compatibility with second-generation Smart HJC Bluetooth systems for seamless communication on the road.
