The HJC RPHA 31 is a premium open-face motorcycle helmet designed for riders who want dependable protection, reduced wind noise, and comfortable all-day performance. This Solid White Small model features HJC’s Premium Integrated Matrix (PIM) Evo shell, which combines carbon-aramid hybrid and natural fiber reinforcement materials for enhanced shock resistance, light weight, and riding comfort. The multi-density EPS liner supports effective impact energy management, while the aerodynamically refined shell helps reduce air resistance and improve stability at highway speeds.
The integrated smoke-tinted sun visor is anti-fog coated and deploys through a convenient bottom-positioned mechanism. Its multi-step adjustment system allows the visor to move closer to the rider’s face for more personalized shading. The included Pinlock® 120XLT® DKS467-ready HJ-39 shield provides 99% UV protection and features an anti-scratch coating for lasting clarity. A redesigned shield holder helps reduce noise and aerodynamic drag while maintaining a secure visor fit.
Ventilation is provided by two intake vents and four exhaust vents to promote full front-to-back airflow. The RPHA Premium Fit interior uses advanced antibacterial fabric with moisture-wicking and quick-drying properties. Removable, washable crown and cheek pads, 3D-contoured cheek pads, and interchangeable cheek pads across sizes support a precise, customizable fit. Reflective materials add visibility in low-light conditions. The helmet also accommodates second-generation SMART HJC Bluetooth communication systems, sold separately, for integrated rider communication.
This HJC RPHA 31 is manufactured by HJC and supplied under vendor part number JA19NUS4XWHV. It is sized Small and finished in Solid White. The elongated shell and extended chin EPS provide a more encompassing fit than a traditional open-face helmet while preserving the convenience and visibility expected for urban, touring, and everyday motorcycle riding.
