The HJC RPHA 31 open-face helmet combines a Premium Integrated Matrix (PIM) Evo shell with multi-density EPS to provide enhanced shock-resistant performance, comfort, and lightness. Its aerodynamic shell design helps reduce air resistance and provide stability at high speed, while wind tunnel development supports a quiet, refined ride.

A Pinlock 120XLT DKS467-ready HJ-39 shield provides 99% UV protection and features an anti-scratch coating. The integrated smoke-tinted sun visor includes an anti-fog coating, a bottom-positioned operating system, and multi-step adjustment that allows positioning up to 10 mm closer to the face for personalized shading and comfort. The shield holder helps reduce noise and drag forces while holding the visor securely.

Full front-to-back airflow is supported by two intake vents and four exhaust vents. The RPHA Premium Fit interior uses advanced anti-bacterial fabric with moisture-wicking and quick-drying function. Removable, washable crown and cheek pads, 3D contour cheek pads, and interchangeable cheek pads throughout all sizes support a customized fit. Reflective material adds visibility, and the helmet accommodates second-generation SMART HJC Bluetooth communication systems, sold separately.
