HJC RPHA91 Carbon Matte Black

HJC RPHA 91 Carbon - RPHA flip-up helmet, dual P/J certified, with a hinged chin bar

The HJC RPHA 91 Carbon is part of the RPHA line of modular helmets, featuring a hinged chin bar that reduces wind noise and air drag compared to the RPHA 90. Dual P/J certified, it features a DMS sun visor and dedicated brow vents designed to prevent fogging.

HJC RPHA 91 Carbon Flip-Up Helmet: Compact, Quiet, and P/J-Certified

The RPHA 91 Carbon was designed to address one of the main criticisms of modular helmets: the noise and drag generated by the chin bar when it's open. Its pivoting chin bar reduces wind noise and air drag in a helmet that is slimmer and more compact than the RPHA 90, while remaining certified in both the closed and open positions thanks to its P&J locking system, which locks and releases the chin bar in the open position for safe riding.

In terms of materials, the shell of this Carbon version is made of P.I.M.(TM)--Premium Integrated Matrix, a fiber fabric infused with epoxy resin, available in four shell sizes for a more precise fit. The shell's aerodynamic design improves airflow.

In front of you, the Pinlock-ready HJ-37 visor--lens included in the box--blocks 99% of UV rays. The helmet features a 3-stage adjustable DMS sun visor, complemented by brow vents that prevent the sun visor from fogging and improve airflow. The ACS ventilation system distributes air through 4 inlets and 6 outlets, and the RPHA 91 Carbon remains compatible with the 2nd-generation HJC SMART 11B, 21B, and 50B Bluetooth systems, sold separately.

Why choose the HJC RPHA 91 Carbon?

The RPHA 91 Carbon is designed for riders who want a discreet and quiet modular helmet, even with the chin bar open. Its hinged chin bar--thinner and more compact than that of the RPHA 90--significantly reduces wind noise and drag, a feature often overlooked in traditional modular helmets.

The dedicated brow ventilation designed to prevent the visor from fogging is a technical feature rarely found on other helmets, which improves visual comfort in humid conditions. Its 5-year warranty further underscores the helmet's premium positioning within the RPHA collection.

Comfort and Ventilation

The RPHA 91 Carbon's ACS system distributes air through 4 intakes and 6 vents, one of the most generous configurations in the RPHA modular lineup. The antibacterial, removable, and washable interior complements this design, featuring interchangeable cheekpads across all sizes.

Articulated Chin Bar and P/J Certification

The chin bar pivot mechanism has been specifically redesigned to reduce noise and drag when open, while maintaining P/J certification that allows you to ride legally with the chin bar raised. The P&J locking system secures this position for confident riding.

DMS Sun Visor and Brow Ventilation

The DMS system allows the sun visor to be adjusted to 3 distinct positions, while the dedicated brow ventilation specifically defogs the sun visor and improves airflow in that area--a welcome comfort feature in humid weather.

Care Instructions

Clean the HJC RPHA 91 Carbon visor with lukewarm water and a soft microfiber cloth, avoiding any harsh household cleaners that could cause scratches on the anti-scratch coating.

Since the inner liner and cheekpads are removable, wash them regularly by hand with mild soap, then let them air dry away from direct heat sources.

Periodically check that the chin bar hinge and the P&J locking system are working properly to ensure your helmet remains reliable over time.
