Always ensure the chin bar is fully locked in either position before riding.

Hand wash them with mild soap and lukewarm water, or follow specific washing instructions provided with the helmet. Allow them to air dry completely before re-installing. Ensure all padding is correctly re-installed for proper fit and protection.
6.3. Entretien de la visière
Clean visors with a soft cloth and lukewarm water. For stubborn dirt, use a specialized helmet visor cleaner. Do not use abrasive materials or harsh chemicals. The Pinlock anti-fog insert (if included) should be cleaned carefully with a soft, damp cloth only, avoiding rubbing. Store the helmet in its bag to prevent scratches.
6.4. Stockage

- Formation de buée sur la visière : Ensure the Pinlock insert is correctly installed (if applicable). Open vents for increased airflow. Consider using anti-fog sprays.
- Le casque est trop serré/trop lâche : Re-check your head measurement against the size chart. Helmet padding will compress slightly over time, but a helmet should never be uncomfortably tight or dangerously loose.
- Bruit excessif du vent : Ensure all vents are closed if not needed. Check that the visor is fully closed and sealed. A snug fit is essential for minimizing noise.
- Mentonnière non verrouillée : Ensure no debris is obstructing the locking mechanism. Apply gentle, firm pressure until it clicks into place. If the issue persists, contact support.
