Description
Schuberth's Dual Locking System (SDL) is a sophisticated, high-precision mechanism designed for their top-tier racing helmets, such as the SP1 Carbon Evo and SK1. It ensures secure and glove-friendly visor operation, featuring one lever for smooth opening and another for a fully sealed, fog-resistant position. This creates a thermal barrier that enhances visibility and focus, essential for motorsport and track performance, while offering improved locking and faster installation compared to older systems.
