The HJC RPHA 31 is an open-face helmet designed with a Premium Integrated Matrix (PIM) Evo shell and multi-density EPS to support shock-resistant performance, comfort, and reduced weight. Its aerodynamic shell shape helps reduce air resistance and provide stability at speed, while wind tunnel development contributes to a quieter, more refined ride.

For airflow management, the RPHA 31 features two intake vents and four exhaust vents to promote front-to-back ventilation. The integrated smoke-tinted sun visor uses an anti-fog coating and can be deployed through the bottom-positioned operating system. Its multi-step adjustment allows the visor to be positioned closer to the face for personalized shading and comfort.

The helmet includes a Pinlock 120XLT DKS467-ready HJ-39 shield with an anti-scratch coating and 99% UV protection. A shield holder helps reduce noise and drag while securing the visor. The RPHA 31 also accommodates second-generation SMART HJC Bluetooth communication systems, sold separately.

Inside, the RPHA Premium Fit interior uses advanced antibacterial fabric with moisture-wicking and quick-drying properties. Removable, washable crown and cheek pads, 3D-contour cheek pads, interchangeable cheek pads across sizes, and reflective material support comfort, customization, and visibility. The helmet is finished in solid matte black and offered in size 2XL.
