The HJC C91 JYN MC5 Modular Helmet combines a polycarbonate composite shell with adjustable chinbar functionality for a lightweight design and comfortable fit. Advanced CAD technology supports the helmet’s fit and comfort, while the double D-ring chin strap provides a secure closure.

HJC’s Advanced Channeling Ventilation System is designed to move air from the front to the back, helping flush 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.

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

Glasses grooves accommodate riders who wear eyeglasses or sunglasses, while interchangeable cheek pads can be used throughout all shell sizes. The helmet also includes speaker pockets and is ready for SMART HJC Bluetooth communication, with Bluetooth sold separately.
