The HJC RPHA 31 is a premium open-face motorcycle helmet designed for riders who want advanced protection, low noise, and long-distance comfort. This Large helmet features HJC’s Premium Integrated Matrix (PIM) Evo shell, combining Carbon-Aramid Hybrid and natural fiber reinforcement materials for enhanced shock resistance, light weight, and durability. The elongated shell and extended chin EPS provide a more encompassing full face-level fit while maintaining the convenience of an open-face design.
Wind-tunnel-developed aerodynamics help reduce air resistance, turbulence, and drag for stable performance at highway speeds. Two intake vents and four exhaust vents create full front-to-back airflow, while the shield holder helps reduce noise and keeps the face shield securely positioned. The included HJ-39 Pinlock 120XLT DKS467-ready shield offers 99% UV protection and an anti-scratch coating. An integrated smoke-tinted sun visor with anti-fog treatment deploys through the bottom-positioned mechanism and features multi-step adjustment, including positioning up to 0.4 inches closer to the face for personalized shading.
The RPHA Premium Fit interior uses advanced antibacterial fabric with moisture-wicking and quick-drying performance. Removable and washable crown and cheek pads, along with 3D-contoured cheek pads and interchangeable sizing options, support a customized fit. Reflective materials improve visibility in low-light conditions. The helmet is also compatible with second-generation SMART HJC Bluetooth communication systems, sold separately, allowing riders to add integrated communication without distracting from the road.
