Memphis Shades used Computational Fluid Dynamics (CFD) to study airflow around 3D shapes, analyzing hundreds of variations before testing prototypes in real world riding conditions. The Spoiler Windshield's flipped up profile was designed to deflect turbulence away from the rider and reduce buffeting at highway speeds. For you, that means it can run shorter than a traditional non compound curved windshield while still providing equal or better wind protection. The result is a low, tinted shield with a clean boulevard look and the coverage of a much taller windshield.
