The Motus MST is a sport touring motorcycle that was announced to be produced in 2014 by Motus Motorcycles of Birmingham, Alabama. Motus' partner in developing the MST was race car manufacturer Pratt & Miller, who were credited with product engineering, development, testing and validation for the MST.[3][4]

The MST is powered by a 90° pushrod V4 engine that is mounted longitudinally, with its crankshaft aligned fore-and-aft. It is the first production motorcycle using gasoline direct injection and the first V4 ever used in an American motorcycle.[3]

The prototype was first shown to the public at Daytona Beach Bike Week in March, 2011.[5]
