The HJC C91 JYN MC5 Modular Helmet in Large combines adaptable protection, rider comfort, and convenient touring features in a versatile modular design. Built with an advanced polycarbonate composite shell, this HJC helmet uses CAD technology to provide a lightweight, comfortable fit. The adjustable chin bar allows riders to select an open or full-face configuration, making the C91 suitable for commuting, touring, and everyday street riding.
Airflow is managed by HJC’s Advanced Channeling Ventilation System (ACS), which directs fresh air from the front of the helmet through internal channels and exhausts heat and humidity from the rear. The Pinlock-prepared HJ-17 face shield provides 99% UV protection and works with a compatible Pinlock insert to help reduce fogging. HJC’s RapidFire Shield Replacement System enables quick, secure, tool-less shield changes, while the integrated black dark smoke sun visor deploys easily with a user-friendly sliding mechanism and anti-scratch coating.
Removable, washable crown and cheek pads use moisture-wicking materials to help maintain a dry interior. Interchangeable cheek pads fit across all shell sizes, and built-in glasses grooves accommodate riders who wear eyeglasses or sunglasses. A Double D-ring chin strap provides a secure closure, while dedicated speaker pockets and compatibility with SMART HJC Bluetooth systems support integrated communication equipment; Bluetooth components are sold separately. The HJC C91 JYN MC5 is sized Large and is identified by manufacturer and vendor part number EP25NUS6805V.
