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.[6]

The prototype was first shown to the public at Daytona Beach Bike Week in March, 2011.[8] 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 (263.90 km/h) and 165.81 mph (266.85 km/h) for the records and a top speed of 168.69 mph (271.48 km/h).[9][10]
