Motorcycle upstart Motus Motorcycles continues to press forward with its MST-01 sport-tourer, and has released a video that talks more about the development of their 1645cc gasoline direct-injection V4 motor: the KVM4. Balking at the advice of others not to build their own powerplant, Motus has teamed up with Katech to design an in-house motor for the Motus MST-01.
