HJC Y50 Youth Off-Road Helmets
The HJC Y50 Youth Off-Road Helmet is built specifically for young motocross and off-road riders, combining lightweight protection, ventilation, comfort, and goggle-ready performance. Its APC Advanced Polycarbonate Compound shell delivers strong impact resistance in a youth-specific design, while the ACS Advanced Channeling Ventilation System uses six intake and two exhaust vents to promote steady airflow throughout the helmet. Inside, the BCS Bespoke Contour Liner System helps create a secure, comfortable fit, complemented by a moisture-wicking, quick-drying antibacterial interior made with OEKO-TEX materials. Removable and washable crown and cheek pads simplify cleaning, while interchangeable cheek pads across all sizes allow additional fit customization. A goggle-compatible eye port, secure Double D-Ring closure, and stable aerodynamic peak visor complete the off-road setup. The HJC Y50 is DOT FMVSS 218 and ECE 22.06 homologated.
