HJC i91 – Adventure Modular Helmet, 3-Position DMS Sun Shield, and Dual P/J Approval

The HJC i91 is a modular helmet with a distinctive Adventure style, designed for long-distance riding as well as everyday versatility. Approved for use with the chin bar both closed and open, it features a 3-position adjustable DMS sun shield and generous ventilation with 6 air vents.

HJC i91 Modular Helmet: Versatility and Precise Adjustments

A long-distance Adventure helmet must 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 chin bar that is approved for use both closed and open (P/J).

Its standout feature is the DMS – Dynamic Multi-Step Sunshield system, a sun shield adjustable in 3 positions that allows you to find the optimal setting for the light conditions, rather than a simple on-off mechanism. The scratch-resistant HJ-33 shield, which is Pinlock-ready and includes a lens in the box, filters 99% of UV rays.

For ventilation, the ACS system distributes air through 3 inlets and 6 outlets, one of the most generous configurations in HJC's modular range, designed to effectively expel heat and moisture on long rides. The removable and washable antibacterial fabric interior completes this helmet designed for both touring and everyday use.

Why Choose the HJC i91?

The i91 stands out for the precision of its sun shield adjustment: the 3-position DMS system allows you to find an optimal intermediate setting, rather than a simply raised or lowered shield. This is a real advantage during the gradual changes in light typical of long rides.

Its dual P/J approval and availability up to 3XL also make it a particularly versatile helmet, capable of adapting to mixed road use and a wide range of body types.

Comfort and Ventilation

With 3 inlets and 6 air outlets, the i91's ACS system offers one of the most generous ventilation configurations in HJC's modular range, designed to effectively expel heat and moisture on the longest rides. The removable and washable antibacterial interior completes this approach, with cheek pads that are interchangeable across all sizes.

3-Position DMS Sun Shield

The DMS – Dynamic Multi-Step Sunshield system allows you to adjust the sun shield in 3 distinct positions, offering an optimal setting for the light conditions rather than a binary adjustment. This is a welcome comfort feature for rides where the light changes gradually, such as at sunrise or sunset.

P/J Approval and Versatile Use

Thanks to its dual P/J approval, the i91 can be legally used both with the chin bar closed for maximum protection and with the chin bar raised for a more open experience when stopped or in urban traffic.

Maintenance Tips

Clean the HJC i91 shield with lukewarm water and a soft microfiber cloth, avoiding any harsh household products that could damage the scratch-resistant coating.

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

Periodically check that the openable chin bar and DMS sun shield system are working properly to keep your helmet reliable over time.
