The HJC C91 JYN MC5 is a versatile modular motorcycle helmet designed for riders who want dependable protection, practical comfort, and convenient touring features. This medium-size helmet combines an advanced polycarbonate composite shell with HJC’s CAD technology to provide a lightweight, comfortable fit. The adjustable chinbar allows the helmet to adapt to changing riding conditions, while the secure double D-ring chin strap helps provide a reliable fit.
Designed for improved airflow, the Advanced Channeling Ventilation System (ACS) creates front-to-back ventilation that helps move heat and humidity away from the rider. The Pinlock®-prepared HJ-17 face shield provides 99% UV protection and supports an optional Pinlock® anti-fog insert. HJC’s RapidFire™ shield replacement system allows quick, tool-less shield changes, making maintenance and replacement convenient. An integrated black dark smoke sun visor deploys smoothly with a user-friendly slider and features an anti-scratch coating for added durability.
Interior comfort features include moisture-wicking, quick-drying materials and removable, washable crown and cheek pads. Interchangeable cheek pads across shell sizes help riders fine-tune the fit, while integrated glasses grooves accommodate eyeglasses and sunglasses. The HJC C91 is also ready for SMART HJC Bluetooth communication systems, with built-in speaker pockets for compatible communication equipment; Bluetooth components are sold separately. This HJC medium modular helmet is identified by manufacturer and vendor part number EP25NUS5805V and is designed for motorcycle and powersports riders seeking adaptable full-face coverage for commuting, touring, and everyday road use.
