The HJC RPHA 31 Dereen MC5SF is an open-face motorcycle helmet designed with a Premium Integrated Matrix (PIM) Evo shell and multi-density EPS. Its Carbon-Aramid Hybrid and Natural Fiber reinforcement materials provide shock-resistant performance, comfort, and lightness.

An aerodynamic shell developed through wind tunnel testing helps reduce air resistance and improve stability at higher speeds. The helmet features two intake vents and four exhaust vents for front-to-back airflow, while the shield holder helps reduce noise and drag forces and keeps 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 features an anti-fog coating, bottom-positioned operation, and multi-step adjustment, including positioning up to 10 mm closer to the face for personalized shading.

The RPHA Premium Fit interior uses advanced anti-bacterial fabric with moisture-wicking and quick-drying properties. Removable, washable crown and cheek pads, 3D-contour cheek pads, interchangeable cheek pads across sizes, and reflective material support comfort, fit, and visibility. The helmet accommodates second-generation SMART HJC Bluetooth communication systems, sold separately.
