The RPHA 31 offers increased impact resistance and maximum protection thanks to its Premium Integrated Matrix (PIM) Evo shell and multi-density EPS.

Designed for a quieter and more aerodynamic ride thanks to extensive wind tunnel testing, the RPHA 31 equipped with the VISOR sunshield reduces noise and wind turbulence. The RPHA 31 also accepts the second generation of HJC SMART Bluetooth communication systems, allowing riders to stay connected and focused on the road ahead.

Meets or exceeds ECE 22.06 certification. Tests include energy attenuation, penetration resistance, chin bar structural integrity, and labeling requirements for road motorcycle helmets.

The new shell material, including carbon, aramid fiber, carbon, fiberglass, organic non-woven fabric, and natural flax fiber, offers improved impact resistance for a more comfortable and lightweight helmet.

Advanced antibacterial fabric ensures greater breathability and quick drying.
Glaze grooves accommodate goggle wearers.
3D contoured cheek pads.
Reflective material for safety.
Interchangeable cheek pads in all sizes for a personalized fit.
Washable liner and cheek pad.

The RPHA 31 features an extended shell and EPS chin guard to ensure a flush fit compared to traditional open face helmets. It also features an all-new removable visor deflector and visor holder to reduce noise, secure the visor, and block incoming wind. Tested in the lab and in real life to meet the highest quality standards, HJC is one of the very few helmet manufacturers with its own state-of-the-art wind tunnel laboratory for testing aerodynamics, ventilation, noise, and more.

The second-generation SMART HJC premium Bluetooth communication system models feature an all-in-one design, fully integrated into the helmet, allowing you to feel the optimal weight balance and aerodynamic performance while riding. The SMART HJC 50B and 21B can be installed on the RPHA 71, RPHA 91, RPHA 31, or i71. Developed in collaboration with SENA and designed specifically for HJC helmets.
The warranty applies to manufacturer defects for up to 5 years from the date of purchase, or 7 years from the date of manufacture (whichever comes first).
