HJC RPHA-11 - Darter

HJC have pushed themselves to improve on the RPHA and this evolution takes the form of the RPHA 11. Wind tunnel tested to ensure it delivers on the promise of high performance and restructured to offer even better protection.

The shell structure has been redesigned for better performance at high speeds. The rear spoiler has also be redesigned to work with this new structure to increase the aerodynamics of the helmet. Inlet vents on the chin and forehead work to provide a supply of fresh air. This is while outlet vents on the back of the helmet exhaust used air. HJC’s “Advanced Channelling Ventilation System” means that this air supply is evenly distributed so you’ll keep cool no matter how hot it gets. Various layers of fibreglass, aramid and carbon fibre make up HJC’s PIM+ shell design and offers fantastic shock absorption and rigidity. The eye port of the helmet is wider to give better peripheral vision.

After countless hours of lab and track testing HJC has delivered an all new helmet ideal for the serious rider who is after high performance.
