  • Lightweight composite shells, advanced ventilation systems, and comfortable moisture-wicking liners that keep you cool during intense riding sessions.
  • Meets or exceeds DOT and ECE safety standards, providing crucial protection against impacts while maintaining the aggressive styling riders demand.
  • Safety & Protection
    Our MX helmets utilize multi-density EPS foam, reinforced chin bars, and impact-absorbing shell construction to provide maximum protection during crashes and impacts. DOT and ECE certified options ensure you meet competition requirements.

  • Ventilation & Comfort
    Strategic intake and exhaust ports create optimal airflow, preventing heat buildup during aggressive riding. Removable, washable liners wick away moisture while padded cheek pads provide a secure, comfortable fit.

    Lightweight construction reduces neck fatigue during long rides. Extended visors deflect roost and debris while wide eye ports accommodate all goggle styles for seamless integration.

Proper fit is critical for safety and comfort. Measure your head circumference above the eyebrows and refer to manufacturer sizing charts. Helmets should fit snugly without pressure points, with cheek pads making firm contact. Visit our sizing guide for detailed instructions.

GMAX helmets carry a 3-year warranty against defects in materials and workmanship, covering replacement parts or repair, labor and service. Accidents, normal wear and tear, and natural breakdown of colors and materials over time aren't covered. Contact us with your receipt and photos and we'll help you start the claim.

Measure around your head about an inch above your eyebrows and compare it to the size chart on this page. A new helmet should feel snug all around with no pressure points, and it shouldn't shift when you shake your head. The liner breaks in a little with use, so if you're between sizes, start with the smaller one.

The size was too small even for an xl. I emailed twice. Never got a response. There’s no phone number to call at. So they won’t return anything you buy. Beware.
