The RPHA 31 has an extended shell & chin EPS to provide full face level fitting compared to classic open-face helmets.
The HJC RPHA 31 Kouv motorcycle helmet offers enhanced shock resistance and maximum protection thanks to its Premium Integrated Matrix (PIM) Evo shell and multi-density EPS. PIM Evo shell includes carbon-aramid fiber, carbon fiber, glass fiber, organic non-woven fabric, and natural linen fiber to provide enhanced Shock-Resistant performance for a more comfortable and lighter helmet.
Engineered for a quieter, more aerodynamic ride through extensive wind-tunnel testing, the sun-visor-equipped RPHA 31 decreases noise level and wind turbulence. The RPHA 31 open-face helmet will also accept the second generation of SMART HJC Bluetooth communication systems, allowing riders to stay connected and focused on the road ahead.
