The HJC F31 Bask MC3HSF is a medium-size motorcycle helmet designed for riders who want a lightweight, comfortable, and adaptable open-face riding experience. Its Advanced Fiberglass Composite (AFC) shell provides a strong, lightweight construction, while the Double-D ring closure with pull tab supports a secure and dependable fit. The manufacturer is HJC, and the vendor part number is JA21NUS54H3V.
Feature: The dynamic multi-step sun shield allows riders to adjust coverage for changing light conditions. The helmet uses an HJ-43 visor that is Pinlock prepared, anti-scratch coated, and provides 99% UV protection. It is also ready for HJC SMART 2nd Generation 11B, 21B, and 50B Bluetooth communication systems, which are sold separately.
Feature: The interior uses moisture-wicking, quick-drying, and odor-resistant materials to help maintain comfort during extended rides. The crown and cheek pads are removable and washable for convenient cleaning. Interchangeable cheek pads can be used across all helmet sizes, helping riders fine-tune the fit and support long-term interior maintenance.
Feature: HJC's Advanced Channeling Ventilation System (ACS) uses three intake vents and one exhaust vent to promote full front-to-back airflow. This ventilation design helps move heat and humidity away from the rider's head for improved comfort. The medium HJC F31 helmet is suited for compatible motorcycle and scooter applications where a secure closure, adjustable sun protection, communication-system readiness, and effective ventilation are important.
