HJC RPHA 12 Carbon

The HJC RPHA 12 is the successor to the legendary RPHA 11, refined for even better performance on the track and the road. The solid-colour variant provides the ideal canvas for custom paintwork, with its smooth composite surface accepting paint beautifully.

HJC's wind tunnel testing and CFD-optimised aerodynamics ensure stability at high speeds, while the Advanced Channeling Ventilation System keeps the rider cool. The wide eye-port offers excellent peripheral vision, and the emergency quick-release cheek pads allow safe helmet removal by first responders. Backed by HJC's 5-year warranty from date of purchase.
