Motus MST

The Motus MST was a sport touring motorcycle produced from 2014 to 2018 by Motus Motorcycles of Birmingham, Alabama. Motus was the newest motorcycle manufacturer in the United States. 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.

The MST was powered by a 90° pushrod V4 engine that was mounted longitudinally, with its crankshaft aligned fore-and-aft. This was the first V4 ever used in an American motorcycle.

The prototype was first shown to the public at Daytona Beach Bike Week in March, 2011. The production MSTR bike was ridden at Bonneville Speedway and set the official land speed record for the world's fastest pushrod-engine production motorcycle, with speeds of 163.98 mph and 165.81 mph for the records and a top speed of 168.69 mph.
