Are you curious about the Motus MST’s noise? Here it is, we finally have an audio track of the bike’s KMV4 engine. Development continues on the MST prototypes, shown here at the prestigious Barber Motorsports Park in Birmingham, Alabama. At the heart of the MST is a 1654cc V4 which is a downsized version of Chevy’s LS7. The 90-degree engine delivers 161 hp at 7,800 rpm and 122 lb.-ft. at 4,500 rpm, while the redline is at 8,000 rpm. The bike tips the scales around 500 lbs dry.
