The HJC C91 modular helmet combines an advanced polycarbonate composite shell with an adjustable chinbar for a lightweight design, fit, and comfort developed using advanced CAD technology. Its modular construction supports flexible riding, while the double D-ring chin strap provides a secure method of fastening.

An Advanced Channeling Ventilation System helps flush heat and humidity from the front of the helmet toward the rear for continuous airflow. The Pinlock-prepared HJ-17 shield provides 99% UV protection, and the RapidFire shield replacement system allows quick, tool-less shield changes using a secure ratchet mechanism.

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, dry interior parts help support comfort, while the removable and washable crown and cheek pads make interior care convenient. Interchangeable cheek pads are available throughout all shell sizes.

Glasses grooves accommodate riders who wear eyeglasses or sunglasses. The helmet also includes speaker pockets and is ready for SMART HJC Bluetooth, with Bluetooth sold separately. The HJC C91 JYN MC3HSF is offered in size 2XL under part number EP25NUS88S3V.
