The HJC C91 modular helmet combines an advanced polycarbonate composite shell with an adjustable chinbar for versatile riding performance. Advanced CAD technology supports a lightweight design with a superior fit and comfortable interior, while the double D-ring chin strap provides secure closure.

The Advanced Channeling Ventilation System (ACS) creates full front-to-back airflow to help move heat and humidity up and out of the helmet. The Pinlock prepared 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. The sun visor features an anti-scratch coating, while the moisture-wicking interior helps maintain a dry feel. Removable and washable crown and cheek pads support convenient care, and interchangeable cheek pads are available throughout all shell sizes.

Glasses grooves accommodate riders who wear eyeglasses or sunglasses. Speaker pockets are provided for Bluetooth communication, and the helmet is ready for SMART HJC Bluetooth, which is sold separately.
