HJC - C91 Solid Modular Helmet - Black | Matte | Semi-Flat
The C91 Solid brings HJC's complete modular feature set to a stealthy matte black finish for riders who want function over flash. The Advanced Polycarbonate Composite Shell is shaped with CAD technology for a lightweight, comfortable fit, and the adjustable chinbar locks securely into place when you want full-face protection. Air routes front-to-back through the Advanced Channeling Ventilation System to flush out heat and humidity, and the Pinlock-prepared HJ-17 shield offers 99% UV protection while swapping tool-less via the RapidFire shield replacement system. A smoke-tinted, anti-scratch sun visor deploys quickly on a user-friendly sliding mechanism. The interior parts are moisture-wicking and stay dry, and the crown and cheek pads are removable, washable, and interchangeable across shell sizes, with glasses grooves for riders who wear eyewear. A double D-ring chin strap locks everything in place, and built-in speaker pockets combined with SMART HJC Bluetooth readiness make it easy to add communication later. Whether you're commuting or heading out on a longer ride, the C91 Solid keeps it simple and dependable.
