The HJC C91 Modular Helmet offers riders a versatile and lightweight solution without compromising on safety or comfort. Engineered with an Advanced Polycarbonate Composite Shell and an adjustable chinbar, this helmet utilizes advanced CAD technology to ensure a superior fit and a lightweight feel for long-distance cruising or daily commutes.
Stay cool and focused with the Advanced Channeling Ventilation System (ACS). This sophisticated design allows full front-to-back airflow to flush heat and humidity up and out of the helmet. For clear vision in various conditions, the Pinlock® Prepared HJ-17 Shield provides 99% UV protection and features the RapidFire™ Shield Replacement System—a simple and secure ratchet system that allows for ultra-quick, tool-less shield replacement. Additionally, an integrated Black Dark Smoke sun visor deploys quickly and easily with a user-friendly sliding system and features an anti-scratch coating.
The interior is designed for maximum rider comfort, featuring moisture-wicking, quick-drying fabrics. Both the crown and cheek pads are fully removable and washable to keep your gear fresh. For added convenience, the interior includes built-in glasses grooves to accommodate riders who wear eyeglasses or sunglasses, and the cheek pads are interchangeable throughout all shell sizes for a customizable fit.
Stay connected on the road with integrated speaker pockets and readiness for the SMART HJC Bluetooth system (Bluetooth sold separately). Whether you are looking for advanced protection or functional versatility, this modular helmet delivers a premium riding experience.
