The one cylinder 4 stroke, 9.1 cubic inch (149 cc) two overhead valve, air cooled engine is plenty peppy enough, producing 12.7 HP at 7,000 revs. Maximum torque: 9.04 ft./lb. at 9,000 revs to support the combined passenger/payload weight with a 12.5 horsepower, single carbureted engine. The starter is a push-button electric and kick type, which can be convenient with a low battery. With a five speed standard, chain drive, transmission (one down, four up, toe only) it’s perfect for small town jaunts but achieves freeway speeds (just) at a top speed of 65, without a passenger.
