The HJC C91 modular helmet combines an advanced polycarbonate composite shell with adjustable chinbar functionality for a comfortable, adaptable riding experience. Advanced CAD technology supports the helmet’s fit and comfort, while the Advanced Channeling Ventilation System (ACS) promotes front-to-back airflow to help move heat and humidity upward and away from the rider.

The Pinlock prepared HJ-17 shield provides 99% UV protection, and the RapidFire Shield Replacement System allows quick, tool-less shield changes through its secure shield ratchet design. A black dark smoke integrated sun visor deploys quickly using the user-friendly sliding system and features an anti-scratch coating.

Moisture-wicking interior parts are designed to help maintain a dry-feeling fit. Removable, washable crown and cheek pads support convenient care, while interchangeable cheek pads across all shell sizes allow further adjustment. Glasses grooves accommodate riders who wear eyeglasses or sunglasses.

The HJC C91 includes a double D-ring chin strap, speaker pockets for Bluetooth communication, and readiness for SMART HJC Bluetooth equipment, which is sold separately.
