The HJC C91 modular helmet combines an advanced polycarbonate composite shell with an adjustable chinbar for a lightweight design focused on fit and comfort. CAD technology supports the helmet’s fit, while the modular configuration provides adjustable chinbar functionality for riding versatility.

An Advanced Channeling Ventilation System provides front-to-back airflow to help move heat and humidity out of the helmet. The Pinlock-ready HJ-17 shield provides 99% UV protection, and the RapidFire shield replacement system enables simple, secure, tool-less shield changes.

A black dark smoke integrated sun visor deploys quickly and easily through a user-friendly sliding system and features an anti-scratch coating. Moisture-wicking interior parts, removable and washable crown and cheek pads, interchangeable cheek pads, and glasses grooves support everyday comfort for 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.
