The HJC RPHA 31 Dereen MC6HSF is an open-face helmet designed for shock resistance, comfort, and aerodynamic stability. Its Premium Integrated Matrix (PIM) Evo shell combines Carbon-Aramid Hybrid and Natural Fiber reinforcement materials to provide a lightweight, comfortable construction with enhanced shock-resistant performance. A multi-density EPS liner further supports the helmet’s protective design.

Developed through wind tunnel testing, the aerodynamic shell helps reduce air resistance and improve stability at high speed while supporting a quiet ride. The helmet features two intake vents and four exhaust vents for front-to-back airflow. A shield holder helps reduce noise and drag forces while holding the visor securely in place.

The Pinlock 120XLT DKS467-ready HJ-39 shield provides 99% UV protection and has an anti-scratch coating. An integrated smoke-tinted sun visor uses an anti-fog coating for clear vision and deploys through the bottom-positioned operation system. Its multi-step adjustment allows the sun visor to be positioned up to 10 mm closer to the face for personalized shading.

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, interchangeable cheek pads across all sizes, and reflective material support comfort, customization, and visibility. The helmet also accommodates second-generation SMART HJC Bluetooth communication systems, sold separately.
