The RPHA 31 offers enhanced impact resistance and maximum protection thanks to the Premium Integrated Matrix (PIM) Evo shell and multi-density EPS. Designed for a quieter, more aerodynamic ride through extensive wind tunnel testing, the sun visor-equipped RPHA 31 reduces noise levels and wind turbulence. The RPHA 31 also accepts second-generation SMART HJC Bluetooth communication systems, allowing riders to stay connected and focus on the road ahead.
