HJC i91 - Flip-up Helmet, 3-position DMS Sun Visor, and Dual P/J Certification

The HJC i91 is a flip-up helmet with a distinct Adventure style, designed for long-distance rides as well as versatile everyday use. Approved for use in both the closed and open positions, it stands out for its 3-position adjustable DMS sun visor and generous ventilation with 6 air vents.

HJC i91 Flip-Up Helmet: Versatility and Fine-Tuning

An adventure helmet for long-distance riding must be able to adapt to changing conditions without requiring frequent stops. The HJC i91 was designed with this in mind, featuring an APC (Advanced Polycarbonate Composite) shell available in three sizes and a flip-up chin guard approved for use in both closed and open positions (P/J).

Its standout feature is the DMS (Dynamic Multi-Step Sunshield) system--a 3-step adjustable sun visor that allows you to find the optimal position based on light conditions, rather than a simple on/off mechanism. In front of you is the HJ-33 visor, which is scratch-resistant and Pinlock-ready--with a lens included in the box--and filters out 99% of UV rays.

For ventilation, the ACS system distributes air through 3 intakes and 6 vents--one of the most generous configurations in HJC's modular lineup--designed to effectively wick away heat and moisture on long rides. The antibacterial fabric lining, which is removable and washable, rounds out this helmet designed for both touring and everyday use.

Why choose the HJC i91?

The i91 stands out for the precision of its sun visor adjustment: the 3-step DMS system allows you to find an optimized intermediate position, rather than simply raising or lowering the visor. This is a real advantage during gradual changes in light conditions, which are typical on long trips.

Its dual P/J certification and availability up to size 3XL also make it a particularly versatile helmet, capable of adapting to mixed road use and a wide variety of head shapes.

Comfort and Ventilation

With 3 air inlets and 6 air outlets, the i91's ACS system offers one of the most generous ventilation configurations in the HJC modular helmet lineup, designed to effectively wick away heat and moisture on even the longest rides. The antibacterial, removable, and washable interior complements this design, with interchangeable cheekpads available across all sizes.

3-Position DMS Sun Visor

The DMS (Dynamic Multi-Step Sunshield) system allows you to adjust the sunshield in 3 distinct steps, offering an optimized position based on light conditions rather than a binary setting. This is a welcome convenience for rides where light changes gradually, such as at sunrise or sunset.

P/J Certification and Versatile Use

Thanks to its dual P/J approval, the i91 can be legally worn with the chin guard closed--for maximum protection--or with the chin guard raised--for a more open fit during stops or while riding in urban traffic.

Care Instructions

Clean the HJC i91's 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 flip-up chin bar and the DMS sun visor system are functioning properly to ensure the helmet remains reliable over time.
