You have to admit, the sound of internal combustion is music to a gearhead's ear. And in the motorcycle world, that frequently means throbbing V-twins and howling inline-4s, not pushrod 90-degree V-4s with roller rockers. So do yourself a favor and click on the link below to listen to the "Baby Block" V-4 that powers the Alabama-built Motus MV4 and MV4R. To us, this powerplant sounds more like a throaty Corvette than a sport-touring motorcycle. Turn it up, but be prepared to attract a crowd to your cubicle!
