Harley-Davidson Model S 125 Hummer - 1948 publicity campaign - motorcycle photo

Description

A superb and rare photo of the
1936 Harley-Davidson factory sidecar
attached to the new
61 c.i. Harley Davidson ES Knucklehead
model.
In 1936 H-D introduced the 61 c.i. (1,000cc) OHV Knucklehead model series. Its massive V-twin overhead valve HD engine performed remarkably well.
Together with the new Knucklehead a new, more modern styling was introduced on the big Harley models. The
Harley-Davidson Knucklehead
engine was named after the distinct shape of the rocker boxes. The V-twin engine featured two valves per cylinder which were operated by pushrods. It was the third type of V-Twin engine used by Harley-Davidson, replacing the Flathead engine in 1936 (which had replaced the F-head or IOE engine on big twins in 1930). The engine was manufactured until 1947 and was replaced by the Panhead engine in 1948. As the design of Harley-Davidson engines has evolved through the years, the distinctive shape of the valve covers has allowed Harley enthusiasts to classify an engine simply by looking at the shape of the cover. A knucklehead engine has round knobs on the cover resembling knuckles that give the knucklehead its name.
This photograph shows the 1936 sidecar, attached to the H-D ES (sidecar version) Knucklehead model.
