Metallic Security Badge

  • This small metallic triangle is an exclusive LS2 feature that further strengthens the helmet strap connection.

Emergency Release System

  • The emergency release system allows the emergency service to remove the helmet pads and thus create an additional space for the removal of the helmet with minimal movement of the head and neck of the victim. It is recommended that someone hold the helmet to avoid movements of the same when removing the cushions. Slide your finger into the red loop and pull it gently to remove the cushions. Slide the side cushions over the belts and remove them from the helmet.


  • LS2 visors are made from 3D optically correct “A-Class” Polymers, a polymer from space research with high resistance to impact energy and maximum visibility. The visors are stable, scratch-resistant and UV-resistant. All this combined with the ultimate PINLOCK technology offers the most advanced anti-fog standard.

Quick Dismount System

  • This system (patent pending) simplifies changing the sight with your bare hands. The spring suspension built in with a locking pin ensures a perfect fit without air gaps when the visor is closed.

Comfort lining

  • All LS2 helmets have removable and washable lining to keep them as fresh as new. Our anatomically correctly designed cheek pads are based on LS2 3D laser technology and offer a perfect fit. Hypoallergenic substances are used which remove the moisture in order to ensure the driver always pleasant conditions.

chin strap

  • A high quality fabric placed in front of the chin reduces the airflow impinging on the driver's face and allows more comfortable driving. The chin strap can be removed when hot.


  • Hypoallergenic substances are used which support the moisture transport and ensure a pleasant wearing comfort.

Laser cut pads

  • Foam with different densities is cut into 3D by a laser and fits perfectly to the driver's head shape.
