The HJC F31 Bask MC3HSF 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 seeking a comfortable, aerodynamic fit with dependable protection and convenient eye-shield performance. The HJC F31 uses the HJ-43 visor, which is Pinlock prepared, anti-scratch coated, and provides 99% UV protection. Its dynamic multi-step sun shield allows riders to select an optimized position as lighting conditions change.
Comfort is supported by a moisture-wicking, quick-drying, and odor-free interior. The crown and cheek pads are removable and washable for easier maintenance, while interchangeable cheek pads across all helmet sizes help support a more personalized fit. A Double-D ring closure with pull tab provides a secure, traditional fastening system. The HJC F31 also features an Advanced Channeling Ventilation System (ACS) that uses three intake vents and one exhaust vent to create full front-to-back airflow, helping move heat and humidity away from the rider.
The helmet is ready for the SMART HJC 2nd Generation 11B, 21B, and 50B Bluetooth communication systems, which are sold separately. The manufacturer is HJC, and the vendor part number is JA21NUS44H3V. This product is sized Small and identified by the model designation F31 Bask MC3HSF. Fitment is intended for riders whose head measurements correspond to HJC's Small size; confirm the manufacturer's sizing guidance and shell-fit recommendations before purchase.
