HJC RPHA 91 – P.I.M.™ Modular Helmet, Dual P/J Approved with Articulating Pivot Chin Guard

The HJC RPHA 91 incorporates the award-winning modular architecture of the RPHA range in a premium P.I.M.™ shell. An articulating pivot chin guard reduces noise and drag, while the DMS sun shield and dual P/J approval retain much of the RPHA 91 Carbon's technology, with a 5-year warranty.

HJC RPHA 91 Modular Helmet: Compact, Quiet and P/J Approved

The RPHA 91 was designed to address one of the main criticisms of modular helmets: the noise and drag generated by the chin guard in the open position. Its articulating pivot chin guard reduces wind noise and drag in a thinner, more compact helmet than the RPHA 90, while remaining approved in both the closed and open positions thanks to its P&J locking system.

Its P.I.M.™ shell – Premium Integrated Matrix, a high-performance material made of epoxy resin-infused fibrous fabrics, is available in four shell sizes for a more refined fit. Its aerodynamic design improves airflow penetration, and the shell has been wind tunnel tested to confirm this performance.

The HJ-37 visor, Pinlock-ready – 120XLT lens included in the box – filters 99% of UV rays and features a scratch-resistant and anti-fog treatment. The helmet includes a 3-position adjustable DMS sun shield, and the ACS ventilation system distributes air through 4 inlets and 6 outlets. The RPHA 91 remains compatible with the SMART HJC 11B, 21B and 50B 2nd Generation Bluetooth systems, sold separately.

Why Choose the HJC RPHA 91?

The RPHA 91 provides access to the core technology of the RPHA 91 Carbon – articulating pivot chin guard, DMS sun shield, P/J approval – with a P.I.M.™ shell that uses high-performance fibrous fabrics rather than carbon. Its 5-year warranty confirms the helmet's premium positioning within the RPHA collection.

Its chin guard, which is thinner and more compact than that of the RPHA 90, significantly reduces wind noise and drag in the open position, a point often overlooked on conventional modular helmets.

Comfort and Ventilation

The RPHA 91's ACS system distributes air through 4 inlets and 6 outlets, one of the most generous configurations in the RPHA modular range. The antibacterial, removable, and washable interior completes this approach, with cheek pads that are interchangeable across all sizes.

Articulating Pivot Chin Guard and P/J Approval

The chin guard's pivot mechanism has been specifically redesigned to reduce noise and drag in the open position, while retaining P/J approval, allowing you to ride legally with the chin guard raised. The P&J locking system secures this position for confident use.

HJ-37 Visor and DMS Sun Shield

The HJ-37 visor features a scratch-resistant and anti-fog treatment, Pinlock readiness, and a lens included in the box. The 3-position adjustable DMS sun shield allows you to adapt precisely to changes in light.

Care Instructions

Clean the HJC RPHA 91 visor with lukewarm water and a soft microfiber cloth, avoiding any harsh household products that could damage the scratch-resistant and anti-fog treatment.

As the top liner and cheek pads are removable, wash them regularly by hand with mild soap, then leave them to air dry away from a direct heat source.

Periodically check that the chin guard pivot and P&J locking system are working correctly to ensure the helmet remains reliable over time.
