The HJC RPHA 12N Red Bull Austin GP II Helmet combines a lightweight PIM EVO shell with aerodynamic design features for stable performance at high speeds. Its optimized shell shape and rear spoiler help reduce lift and drag, while the wind tunnel tested construction supports confident riding performance.

The HJ-42 curved shield works with a 2-way pivot ratchet system to help reduce air drag and noise while creating a tighter seal against the elements. The shield is Pinlock® 120XLT® prepared for added convenience and visibility support in changing riding conditions.

Inside, the RPHA Premium Fit Interior includes removable and washable crown and cheek pads, interchangeable cheek pads across all sizes, and 3D contour cheek pads for a customizable fit. Anti-bacterial fabric provides moisture-wicking and quick-drying performance, while the advanced channeling ventilation system helps support airflow.

The PIM EVO shell incorporates carbon-aramid fiber, carbon fiber, glass fiber, organic non-woven fabric, and natural linen fiber for enhanced shock-resistant performance in a comfortable, lightweight structure. An emergency pull tab and emergency cheek-pad kit support quick helmet removal and rescue access in critical situations. Reflective material adds visibility-focused detailing.
