The HJC RPHA 12N Respon MC27SF motorcycle helmet combines advanced protection, aerodynamic performance, and customizable comfort for street and sport riding. Built with HJC Premium Integrated Matrix EVO (PIM EVO) construction, the shell incorporates carbon-aramid fiber, carbon fiber, fiberglass, organic non-woven fabric, and natural linen fiber. This multi-material design helps deliver a lightweight, impact-resistant structure while supporting long-ride comfort and dependable protection.
Wind-tunnel testing informed the aerodynamic shell shape and optimized rear spoiler, helping reduce lift and drag for improved stability at higher speeds. The HJ-42 curved shield works with a two-way pivot ratchet system to help reduce wind noise and air resistance while maintaining a secure seal against the elements. The shield is Pinlock 120XLT prepared, allowing installation of a compatible anti-fog lens for improved visibility in changing riding conditions.
The RPHA Premium Fit interior is fully removable, washable, and designed for a personalized fit. Interchangeable three-dimensional contour cheek pads can be adjusted throughout all helmet sizes, while antibacterial fabric helps manage moisture through quick-drying and moisture-wicking performance. An advanced channeling ventilation system promotes airflow through the helmet, and reflective material adds visibility in low-light conditions. The integrated emergency pull-tab cheek-pad system allows trained responders to remove the helmet more safely and efficiently during a critical situation.
