The HJC F31 Bask MC5 Helmet combines a lightweight Advanced Fiberglass Composite (AFC) shell with practical touring and street-riding features. This large-size helmet is designed for riders seeking a comfortable fit, effective ventilation, and convenient eye protection. The Double-D ring closure with pull tab provides a secure, traditional fastening system, while the dynamic multi-step sun shield allows optimized positioning for changing light conditions.
The HJC F31 uses an HJ-43 visor with an anti-scratch coating, Pinlock® preparation, and 99% UV protection. Its interior is moisture-wicking, quick drying, and odor resistant to help maintain comfort during extended rides. The crown and cheek pads are removable and washable for easier maintenance, and the interchangeable cheek pads can be used across all helmet sizes to help fine-tune the fit. The helmet is ready for SMART HJC 2nd Generation 11B, 21B, and 50B Bluetooth® communication systems, which are sold separately.
Advanced Channeling Ventilation System (ACS) technology 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 while maintaining a clean, practical exterior profile. The HJC F31 Bask MC5 in Large is identified by manufacturer part number JA21NUS6405V and vendor part number JA21NUS6405V. Fitment is intended for motorcycle riders requiring a large full-face helmet; confirm head measurements and HJC sizing guidance before purchase.
