Description:

The RPHA 31 offers enhanced shock resistance and maximum protection thanks to its Premium Integrated Matrix (PIM) Evo shell and multi-density EPS. 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 will also accept the second generation of SMART HJC Bluetooth communication systems, allowing riders to stay connected and focused on the road ahead.

Key Features:

• Premium integrated matrix / P.I.M EVO: reinforcement materials including carbon-aramid hybrid and natural fibre, provide enhanced shock-resistant performance, more comfort, and lightness of the helmet.
• Aerodynamic design shell reduces air resistance & provides stability at high speed.
• Full front-to-back airflow: 2 intakes and 4 exhausts.
• Pinlock® ready HJ-39 visor: provides 99% UV protection, anti-scratch coated.
• Quick, simple and secure visor (shield) ratchet system.
• Visor deflector decreases noise level and wind turbulence.
• Visor holder reduces noise & drag forces and holds visor tight.
• Adjustable 3-step sun shield for optimised position.
• Light Smoke sun shield installed.
• One-touch buckle (micro buckle)
• Interior with advanced anti-bacteria fabric provides enhanced moisture wicking and quick drying function. Reflective material for safety.
• Crown and 3D contour cheek pads: removable and washable.
• Glasses groves can accommodate riders who wear glasses.
• Ready for SMART HJC 11B, 21B & 50B Bluetooth (sold separately).
• Visor: HJ-39.
• Sun shield: HJ-V12.
• Pinlock®: DKS467.
• ECE 22.06 approved.
   

Technical Features:
PIM EVO Shell
New shell material including carbon-aramid fibre, carbon fibre, glass fibre, organic non-woven fabric, and natural linen fibre to provide enhanced shock-resistant performance for a more comfortable and lighter helmet.

New sun shield mechanism
Integrated Sunshield: anti-fog coated smoke tinted sun visor deploys quickly and easily by bottom positioned new operation system. Its new mechanism allows adjusting the depth in 3 different positions according to your morphology and preference for an optimal fit.

Perfect fit & visor deflector
The RPHA 31 has an extended shell and chin EPS to provide full face level fitting compared to classic open-face helmets. It also comes along with a brand new visor deflector that you can pull out and a visor holder to reduce noise, secures the visor, and block the incoming wind. Tested in the laboratory as well as in "real life" to meet the highest quality standards, HJC is one of the very few helmet companies equipped with its own state-of-the-art wind tunnel laboratory to test aerodynamics, ventilation, noise and more.

Smart HJC 2nd Generation
The SMART HJC 2ndgeneration premium Bluetooth communication system models implement an all-in-one design that is 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 RPHA 71, RPHA 91, RPHA 31, or i71. Co-developed with SENA and tailored specially for HJC helmets. *All SMART HJC devices are sold separately.

5 Year Warranty
Warranty lasts up to 5 years from the date of purchase, or 7 years from the date of manufacturing (whichever comes first).
