The HJC RPHA 31 open-face helmet combines advanced protection, aerodynamic refinement, and everyday comfort in a streamlined design. This N Gray, 2XL model features HJC’s Premium Integrated Matrix (PIM) Evo shell, constructed with reinforcement materials including Carbon-Aramid Hybrid and natural fibers to provide enhanced shock resistance, reduced weight, and a comfortable fit. The multi-density EPS liner is designed to help manage impact energy while the elongated shell and extended chin EPS provide an encompassing, full face-level fit for added coverage.
Engineered through extensive wind-tunnel testing, the HJC RPHA 31 helps reduce air resistance, wind turbulence, and riding noise for a more stable and focused ride. Two intake vents and four exhaust vents create full front-to-back airflow to support ventilation in changing riding conditions. The integrated smoke-tinted sun visor features an anti-fog coating and operates through a convenient bottom-mounted mechanism. Its multi-step adjustment allows the visor to move closer to the face for personalized shading and visibility.
The helmet includes a Pinlock® 120XLT® DKS467-ready HJ-39 shield with anti-scratch treatment and 99% UV protection. A refined shield holder helps reduce noise and drag while securing the visor firmly in place. The RPHA Premium Fit interior uses advanced antibacterial fabric with moisture-wicking and quick-drying properties. Removable, washable crown and cheek pads, three-dimensional cheek-pad contours, reflective material, and interchangeable cheek pads across sizes support a customizable fit and improved visibility. The HJC RPHA 31 also accommodates second-generation SMART HJC Bluetooth communication systems, sold separately, making it a practical fit for riders seeking integrated communication capability.
