1921 Harley-Davidson Model W Sport Twin
In 1909 Harley-Davidson introduced its first V-twin engine, which it used virtually unchanged until 1929. In 1919 the firm attempted to expand its market by offering a new Model W “Sport Twin” that was intended to appeal to entry-level riders. The flat-twin engine aligned the cylinders with the frame, had a modern oiling system, and employed an integrated clutch and transmission, all of which made them smoother and cleaner to ride than their V-twin counterparts. Despite the effort, the Model W did not attract sufficient sales and was discontinued in 1923.
