The HJC F31 Bask MC5 motorcycle helmet combines a lightweight Advanced Fiberglass Composite (AFC) shell with practical touring and street-riding features. This medium helmet is designed for riders seeking balanced protection, comfort, ventilation, and everyday usability. The Double-D ring closure with pull tab provides a secure, adjustable fit, while the removable and washable crown and cheek pads help maintain a clean interior over time.
Visibility and airflow are central to the F31’s design. The HJ-43 visor is Pinlock prepared, anti-scratch coated, and provides 99% UV protection for clearer vision in varying riding conditions. A dynamic multi-step sun shield allows riders to select an optimized position as light conditions change. The Advanced Channeling Ventilation System (ACS) uses three intake vents and one exhaust vent to create front-to-back airflow, helping remove heat and humidity from inside the helmet.
The interior features moisture-wicking, quick-drying, and odor-resistant materials for improved comfort during extended rides. Interchangeable cheek pads across all helmet sizes support flexible fit adjustment and replacement options. The helmet is ready for HJC SMART 2nd Generation Bluetooth systems, including the 11B, 21B, and 50B units, which are sold separately. The HJC F31 Bask MC5 in Medium is manufacturer part number JA21NUS5405V and vendor part number JA21NUS5405V. It is suited for riders looking for a comfortable full-face helmet with integrated sun protection, prepared visor technology, and adaptable communication-system compatibility.
