The RPHA 91 is HJC's new modular touring helmet designed for maximum comfort. The new Premium Integrated Matrix EVO shell (P.I.M. EVO) offers improved shock-resistant performance and is lightweight through the use of reinforcement materials such as carbon-aramid, carbon, fiberglass, organic non-woven fabric and linen fiber (natural fiber). The new distortion-free HJ-37 visor and HJ-V17 sun visor provide clear and better peripheral vision for the rider. The chin bar locking system has been designed to perfection and now features a hidden locking point that ensures smooth contact and less pressure on the cheeks. To keep noise levels to a minimum, the RPHA 91 3D-designed low-noise interior aims to significantly reduce road noise. Also included here is the neck roll system to ensure you drown out the noise. For convenience, the EPS design is suitable for riders with glasses. The RPHA 91 also accepts the second generation Smart HJC Bluetooth systems.
