The HJC RPHA 31 is an open-face motorcycle helmet designed for riders who want advanced protection, refined aerodynamics, and everyday comfort. This solid white helmet is offered in size XS and features the Premium Integrated Matrix (PIM) Evo shell, combining carbon-aramid hybrid and natural fiber reinforcement materials for enhanced shock resistance, reduced weight, and improved comfort. The multi-density EPS liner supports energy management while the elongated shell and extended chin EPS provide an encompassing full face-level fit.
Developed through wind tunnel testing, the RPHA 31 shell is shaped to reduce air resistance, wind turbulence, and riding noise while maintaining stability at higher speeds. Two intake vents and four exhaust vents create full front-to-back airflow to help manage temperature during changing riding conditions. The included HJ-39 Shield is Pinlock 120XLT DKS467 ready, anti-scratch coated, and provides 99% UV protection. Its shield holder helps reduce noise and drag while keeping the visor securely positioned.
A built-in smoke-tinted sun visor offers convenient glare protection and features an anti-fog coating for clear viewing. The bottom-positioned operating system enables quick deployment, while multi-step adjustment lets riders position the visor for a more personalized fit. The HJC 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 helmet sizes help provide a precise, comfortable fit. Reflective material adds visibility in low-light conditions.
The RPHA 31 is compatible with second-generation SMART HJC Bluetooth communication systems, sold separately, allowing riders to add connected communication without compromising the helmet's streamlined design.
