HJC RPHA 91 Police Helmet


The RPHA 91 represents HJC's latest iteration in modular touring helmets, meticulously crafted to deliver unparalleled all-day comfort. Its innovative Premium Integrated Matrix EVO shell (P.I.M. EVO) has been strategically engineered to offer elevated levels of shock resistance, all while maintaining a lightweight profile through the incorporation of advanced reinforcement materials such as carbon-aramid, carbon fiber, glass fiber, organic non-woven fabric, and natural linen fiber.

The HJ-37 face shield and HJ-V17 sun visor offer a distortion-free, panoramic view. The refined chin bar locking system ensures seamless engagement and reduced cheek pressure. The 3D-engineered low-noise interior diminishes road noise, while the EPS design accommodates eyewear. The RPHA 91 is also equipped with second-generation Smart HJC Bluetooth systems, underscoring its advanced connectivity.

The HJC RPHA 91 modular helmet is available in standard colors such as Black and White color combinations. Custom colors, trim styles, decal and graphics options are available (shown below).
