The HJC RPHA 31 is a premium open-face motorcycle helmet designed for riders who want dependable protection, refined aerodynamics, and everyday comfort. This XS helmet features HJC’s Premium Integrated Matrix (PIM) Evo shell, combining carbon-aramid hybrid and natural fiber reinforcement for enhanced shock resistance, reduced weight, and a comfortable fit. The elongated shell and extended chin EPS provide full face-level coverage while maintaining the open-face helmet design.
Designed through extensive wind-tunnel testing, the RPHA 31 helps reduce air resistance, wind turbulence, and riding noise for a more stable and comfortable experience at speed. Its ventilation system uses two intake vents and four exhaust vents to promote front-to-back airflow. The integrated smoke-tinted sun visor features an anti-fog coating and a bottom-positioned operating system for quick deployment. Multi-step adjustment allows the visor to move closer to the face for personalized shading and improved coverage.
The included Pinlock 120XLT DKS467-ready HJ-39 shield provides 99% UV protection and features an anti-scratch coating. The shield holder is designed to reduce noise and aerodynamic drag while keeping the visor securely in place. Inside, the RPHA Premium Fit interior uses advanced antibacterial fabric with moisture-wicking and quick-drying properties. The crown and cheek pads are removable and washable, with interchangeable cheek pads across helmet sizes to help riders achieve a precise fit. Reflective materials add visibility in low-light conditions.
