The HJC C91 JYN MC5 modular helmet in Small combines versatile touring performance with rider-focused comfort and protection. Its advanced polycarbonate composite shell uses CAD technology to provide a lightweight, comfortable fit, while the adjustable chinbar allows the helmet to adapt to changing riding conditions. The aerodynamic design is suitable for street, touring, and everyday motorcycle use.
Integrated airflow is managed by HJC’s Advanced Channeling Ventilation System (ACS), which directs fresh air from front to back while helping exhaust heat and humidity. The Pinlock-prepared HJ-17 face shield provides 99% UV protection, and the RapidFire Shield Replacement System allows quick, secure, tool-free shield changes. A built-in black dark smoke sun visor deploys smoothly with an easy-to-use sliding mechanism and features an anti-scratch coating.
The interior is equipped with moisture-wicking, quick-drying materials, along with removable and washable crown and cheek pads for convenient maintenance. Interchangeable cheek pads accommodate fit adjustments across the shell sizes, while integrated glasses grooves provide added clearance for eyeglasses and sunglasses. A double D-ring chin strap helps provide a secure fit. The helmet also includes speaker pockets and is ready for SMART HJC Bluetooth communication systems, sold separately.
