Fiber jet helmet with transparent visor, retractable sun visor, removable and washable interior, ready for any intercom.

The RPHA 31 offers greater impact resistance and maximum protection thanks to the 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 sun visor reduces noise levels and wind turbulence. The RPHA 31 also accepts the second generation of SMART HJC Bluetooth communication systems, allowing riders to stay connected and focused on the road ahead.
Meets or exceeds ECE 22.06. 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, provides improved impact resistance performance for a more comfortable and lightweight helmet.
Advanced antibacterial fabric provides increased breathability and quick drying.
Glaze grooves accommodate riders who wear glasses
3D contoured cheek pads
Reflective material for safety
Interchangeable cheek pads in all sizes for a custom fit.
Washable liner and cheek pad.
The RPHA 31 features an extended shell and EPS chin guard to provide a flush fit against the face compared to traditional open face helmets. It also features an all-new removable VISOR deflector and VISOR holder to reduce noise, secure 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 companies with its own state-of-the-art wind tunnel lab to test aerodynamics, ventilation, noise and more.
The second generation SMART HJC premium Bluetooth communication system models implement an all-in-one design, fully integrated into the helmet, allowing you to feel the optimal weight balance and aerodynamic performance while riding. SMART HJC 50B and 21B can be installed on RPHA 71, RPHA 91, RPHA 31 or i71. Developed in collaboration with SENA and made specifically for HJC helmets.
The warranty is applicable to manufacturer defects up to 5 years from the date of purchase, or 7 years from the date of manufacture (whichever comes first).
