The HJC RPHA 12N Red Bull Austin GP II motorcycle helmet combines advanced protection, aerodynamic performance, and a customizable fit for demanding street and track riders. Built with HJC Premium Integrated Matrix EVO (PIM EVO) construction, the shell uses a blend of carbon-aramid fiber, carbon fiber, glass fiber, organic non-woven fabric, and natural linen fiber to deliver strong impact resistance with a lightweight feel. This XL helmet is wind-tunnel tested, and its optimized shell shape and rear spoiler help reduce lift and drag for improved stability at high speeds.
The HJC HJ-42 curved shield uses a 2-way pivot ratchet system to help reduce aerodynamic turbulence and wind noise while maintaining a secure seal against the elements. The shield is Pinlock 120XLT prepared for improved fog resistance when paired with a compatible lens. An advanced channeling ventilation system promotes airflow through the helmet, while the RPHA Premium Fit Interior uses antibacterial fabric designed to wick moisture and dry quickly during extended rides.
Comfort and fit can be adjusted with removable, washable crown and cheek pads, plus interchangeable 3D contour cheek pads available throughout all sizes. The emergency pull-tab system and included emergency cheek-pad kit support faster helmet removal by trained responders when necessary. Reflective material adds visibility in low-light conditions. The HJC RPHA 12N Red Bull Austin GP II, manufacturer and vendor part number FA53NUS7F21V, is designed for motorcycle riders seeking a performance-focused full-face helmet with race-inspired aerodynamics, ventilation, premium materials, and adaptable interior comfort.
