The HJC C91 Solid Helmet combines an advanced polycarbonate composite shell with CAD-developed fit and comfort features. Its adjustable chinbar supports versatile riding use, while the lightweight shell construction is designed for a comfortable fit.

The Advanced Channeling Ventilation System provides front-to-back airflow to move heat and humidity upward and out of the helmet. 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 ratchet mechanism.

A built-in dark smoke sun visor deploys quickly with a user-friendly sliding system and features an anti-scratch coating. Moisture-wicking interior parts help maintain a dry feel, while the removable, washable crown and cheek pads support convenient maintenance. Interchangeable cheek pads are available throughout all shell sizes.

Additional features include glasses grooves for riders who wear eyeglasses or sunglasses, a double D-ring chin strap, and speaker pockets for Bluetooth communication. The helmet is ready for SMART HJC Bluetooth, which is sold separately.
