c1913 Harley-Davidson 9B 575cc Motorcycle

Description

With a history dating back to 1903, America's oldest motorcycle manufacturer, Harley-Davidson, was founded in a wooden shed in Milwaukee, Illinois by William S Harley and Arthur Davidson. Early Harleys were all singles and despite the introduction of the V-twin that would become synonymous with the company in 1909, one lungers remained popular and a new model was introduced in 1913. Designated the Model 9, the engine now had a displacement of 35 cubic inches and developed five horsepower, hence the use of the 5-35 moniker. Available in both belt-driven (Model 9A) and chain-driven (Model 9B) versions, the new single was an air-cooled four-stroke unit employing a Schebler carburettor and had a range of improvements over Harley's earlier motors, including a mechanically-operated intake valve, lighter alloy pistons and a balanced flywheel, rod and piston for smoother operation. Only sold in one colour, grey, the Model 5-35 was a strong performer and had a top speed of 55 mph. Priced at $290, or some $60 less than the Model 9E V-twin, the new single proved popular with those who couldn't necessarily afford the luxury of two cylinders. Easily tuned, these early Harleys also proved popular with amateur racers. Just 1,510 were made and few survive today although examples of the 9B grace some of the finest collections around the globe, including the Smithsonian Institute. All Harley singles share the same attributes of simplicity, reliability and good economy and they remained integral to the company's success well into the 1930s.
