RPHA 31 Helmet - Solid - N Gray - Large

The HJC RPHA 31 is a premium open-face motorcycle helmet designed for riders who want dependable protection, reduced wind noise, and long-distance comfort. This Solid N Gray model in Large uses HJC’s Premium Integrated Matrix (PIM) Evo shell, combining Carbon-Aramid Hybrid and natural fiber reinforcement materials for enhanced shock resistance, lightness, and comfort. The multi-density EPS liner helps manage impact energy while the aerodynamic shell design reduces air resistance and improves stability at highway speeds.

Wind tunnel development supports a quieter, more refined ride, while the full front-to-back ventilation system uses two intake vents and four exhaust vents to promote continuous airflow. The integrated smoke-tinted sun visor features an anti-fog coating and a bottom-mounted operating system for quick deployment. Its multi-step adjustment allows the visor to move closer to the rider’s face for personalized shading. The included Pinlock® 120XLT® DKS467-ready HJ-39 shield provides 99% UV protection and includes an anti-scratch coating. The shield holder helps reduce noise and drag while keeping the visor securely positioned.

The RPHA Premium Fit interior uses advanced antibacterial fabric with moisture-wicking and quick-drying performance. Removable, washable crown and cheek pads make maintenance convenient, while 3D-contoured cheek pads, reflective material, and interchangeable cheek pads across sizes support a secure, customized fit. The elongated shell and extended chin EPS create a fuller face-level fit than many traditional open-face designs. The helmet also accommodates second-generation SMART HJC Bluetooth communication systems, sold separately, for integrated rider communication.
