SKU: N/A Brand:

The RPHA 11 is a top-of-the-range sports helmet, specially designed and wind-tunnel tested for the highest aerodynamic performance on the race track. The shell is structured from HJC’s signature Premium Integrated Matrix composition (PIM Plus) consisting of aramid, fibreglass and carbon-fibre for incredible shock-resistance and a lightweight feel on your head, with rear integrated spoiler for reduced buffeting and cutting through the air.

Speaking of air, ventilation at the chin and forehead work to provide fresh air to your face, with outlets on the back to exhaust warm air. The shell’s advanced channelling ventilation system means that the air supply is evenly distributed, with a moisture-wicking multi-cool lining for keeping you comfortable throughout.

The helmet’s eye port is wider to give better peripheral vision, and an emergency cheek pad system allows you to quickly remove your helmet in the event of an accident. A Rapid-fire shield replacement system allows for quick removal and installation, and anti-fog lens included as standard.
