Troubleshooting

Helmet feels too tight in specific spots

The shell is designed to flex. Wear it for short sessions to allow the inner padding and segmented shell to break in and conform to your head shape.

Goggles do not seal properly

Ensure your goggles are designed for motocross use and adjust the strap tension. The Moto-9S eyeport is wide, so ensure the goggle frame is centered.

Pros and Cons

  • Adaptive fit through segmented shell construction
  • Effective reduction of rotational force transfer

  • Professional-grade features come at a premium price point

Setup, Compatibility & Care

To ensure optimal performance, start by measuring the circumference of your head one inch above your eyebrows to find your correct size. When putting the helmet on, ensure it sits level on your brow; the segmented shell will naturally form to your cranium over the first few uses. Compatibility with various goggles is high due to the wide eyeport design. For care, remove the removable comfort liner and wash it using mild soap and cool water, allowing it to air dry completely. The outer shell can be wiped down with a soft, damp microfiber cloth. Never use harsh solvents or chemicals on the shell as they can compromise the structural integrity of the composite materials.
