The HJC F31 Bask MC1SF motorcycle helmet combines a lightweight Advanced Fiberglass Composite (AFC) shell with practical touring and street-riding features. This small-size helmet is designed for riders who want dependable protection, comfortable airflow, and convenient visibility control in a streamlined open-face configuration. The HJC F31 model includes a Double-D ring pull-tab closure for a secure, adjustable fit.
Visibility is managed with the included HJ-43 visor and a dynamic multi-step sun shield that allows optimized positioning while riding. The visor is Pinlock prepared, anti-scratch coated, and provides 99% UV protection. The helmet is also ready for HJC SMART 2nd Generation 11B, 21B, and 50B Bluetooth communication systems, which are sold separately. These features make the F31 Bask MC1SF suitable for daily commuting, touring, and general street use.
The interior uses moisture-wicking, quick-drying, and odor-free materials to help maintain comfort during extended rides. The crown and cheek pads are removable and washable for easier cleaning and maintenance. Interchangeable cheek pads across all helmet sizes support convenient replacement and fit adjustment. HJC’s Advanced Channeling Ventilation System (ACS) uses three intake vents and one exhaust vent to promote full front-to-back airflow, helping move heat and humidity away from the rider.
Manufactured by HJC, the helmet is identified by manufacturer part number JA21NUS44S1V and vendor part number JA21NUS44S1V.
