The HJC RPHA 31 is a premium open-face motorcycle helmet designed for riders who want dependable protection, reduced wind turbulence, and everyday comfort. This Small helmet features a solid N Gray finish and uses HJC’s Premium Integrated Matrix (PIM) Evo shell, combining carbon-aramid hybrid and natural-fiber reinforcement materials for enhanced shock resistance, reduced weight, and improved comfort. The multi-density EPS liner helps manage impact energy while the aerodynamic shell promotes stability and reduced air resistance at highway speeds.
Engineered for a quieter ride, the HJC RPHA 31 uses a shield holder that helps reduce noise and drag while keeping the face shield securely positioned. The included HJ-39 shield is Pinlock 120XLT DKS467 ready, features an anti-scratch coating, and provides 99% UV protection. An integrated smoke-tinted sun visor with an anti-fog coating deploys through the bottom-mounted control system. Its multi-step adjustment allows the visor to move closer to the rider’s face for personalized shading and visibility.
Ventilation is provided by two intake vents and four exhaust vents to support continuous front-to-back airflow. 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, while 3D-contoured cheek pads and interchangeable sizing options help riders achieve a secure, customized fit. Reflective materials add visibility in low-light conditions.
The HJC RPHA 31 accommodates second-generation SMART HJC Bluetooth communication systems, sold separately, for integrated rider communication and audio functionality. Its elongated shell and extended chin EPS provide a more encompassing full-face-level fit while retaining the convenience of an open-face design. Manufacturer: HJC. Vendor part number: JA19NUS4XGNV.
