The HJC C91 modular helmet combines an adjustable chinbar with an advanced polycarbonate composite shell for a comfortable, adaptable riding experience. Advanced CAD technology supports the helmet’s fit and comfort, while the modular design allows the chinbar to be adjusted as needed.

An Advanced Channeling Ventilation System provides front-to-back airflow to help move heat and humidity up and out. The Pinlock prepared HJ-17 shield offers 99% UV protection, and the RapidFire shield replacement system enables quick, tool-less shield changes with its secure ratchet design.

A black dark smoke integrated sun visor deploys quickly through a user-friendly sliding system and features an anti-scratch coating. The removable, washable crown and cheek pads use moisture-wicking materials, while interchangeable cheek pads work throughout all shell sizes. Glasses grooves accommodate riders who wear eyeglasses or sunglasses.

The helmet uses a double D-ring chin strap and includes speaker pockets for Bluetooth communication. It is ready for SMART HJC Bluetooth, which is sold separately.
