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

HJC's Advanced Channeling Ventilation System is designed to move air from front to 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, secure, tool-less shield changes.

A built-in black dark smoke sun visor deploys quickly through a user-friendly sliding system and features an anti-scratch coating. Moisture-wicking, quick-dry interior parts help manage comfort, while the removable and washable crown and cheek pads make care more convenient. Interchangeable cheek pads work 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 communication equipment, which is sold separately. The HJC C91 JYN MC5 is offered in a medium size.
