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

Integrated airflow is provided through two intakes and four exhausts for full front-to-back ventilation. The Pinlock 120XLT DKS467-ready HJ-39 shield provides 99% UV protection and has an anti-scratch coating. A built-in 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.

The RPHA Premium Fit interior uses advanced antibacterial fabric with moisture-wicking and quick-drying properties. Crown and cheek pads are removable and washable, with 3D-contoured cheek pads and interchangeable cheek pads throughout all sizes for a customizable fit. Reflective material adds visibility, while the shield holder helps reduce noise and drag forces and keeps the visor securely in place.

The HJC RPHA 31 accommodates second-generation SMART HJC Bluetooth communication systems, sold separately. Its elongated shell and extended chin EPS support a full face-level fit while maintaining the open-face design. This medium helmet is finished in solid N Gray.
