The Motus MST: an American-made touring motorcycle with the personality of a high-performance, canyon-carving machine. Equipped for comfort mile after mile, the MSTâ€™s untamed side is unleashed on those magical stretches of bent road for which we all ride. Performance. Comfort. Range. The MST, powered by the all-new MV4 â€œBaby BlockÂ®â€ engine twisting out 123 ft lbs of torque, is motion in its purest form.
