The HJC C91 JYN MC1 modular motorcycle helmet combines versatile functionality, rider comfort, and dependable protection in a streamlined design. This small-size helmet features an advanced polycarbonate composite shell developed with CAD technology for a lightweight feel, a precise fit, and comfortable long-distance riding. The adjustable chin bar allows the helmet to transition between configurations, making it suitable for commuting, touring, and everyday motorcycle use. Manufacturer and vendor part number: HJC EP25NUS4801V.
Visibility and airflow are supported by HJC’s Advanced Channeling Ventilation System (ACS), which directs fresh air from front to back while helping move heat and humidity out of the helmet. The Pinlock-ready HJ-17 face shield provides 99% UV protection and is compatible with a Pinlock anti-fog insert. HJC’s RapidFire shield replacement system enables quick, secure, tool-free shield changes, while the integrated dark smoke sun visor deploys easily and includes an anti-scratch coating for added durability.
Inside, moisture-wicking interior materials help keep the rider dry, while removable and washable crown and cheek pads support convenient cleaning and long-term comfort. Interchangeable cheek pads fit across all shell sizes, and integrated glasses grooves accommodate riders who wear eyeglasses or sunglasses. A double D-ring chin strap provides secure fastening, and dedicated speaker pockets support Bluetooth communication. The helmet is ready for the SMART HJC Bluetooth system, which is sold separately. Designed for riders seeking adaptable fitment and all-season usability, the HJC C91 JYN MC1 is sized small and identified by part number EP25NUS4801V.
