Originally designed for the track, the RPHA 11 is HJC's premium sport helmet, engineered with an aerodynamic shell structure for extreme performance at top speeds. The shell composition in Premium Integrated Matrix (P.I.M Plus) offers greater impact resistance and makes the helmet more comfortable and lightweight, thanks to the use of reinforcement materials such as carbon fiber and a hybrid glass and carbon fabric. The features suit sport riders with a widened visor that allows a broader view in a tucked position and an exceptional airflow ventilation system. Additional safety features include reflective strips on the rear side of the helmet and an emergency cheek pad removal system that allows safe and quick helmet release in emergency situations.
