1910 – 1911 Harley-Davidson Model 7D

In 1910 the famed “Bar & Shield” logo is used for the first time. It is trademarked at the U.S. Patent office one year later.

At least seven different first place finishes are captured at races, endurance contests and hillclimbs across America. All seven winners are riding Harley-Davidson® motorcycles.

In 1911, an improved V-Twin model was introduced. The new engine had mechanically operated intake valves, as opposed to the “automatic” intake valves used on earlier V-Twins that opened by engine vacuum. With a displacement of 49.48 cubic inches (810.8 cc), the 1911 V-Twin was smaller than earlier twins, but gave better performance. After 1913 the majority of bikes produced by Harley-Davidson would be V-Twin models.

The “F-head” engine becomes a workhorse of the Harley-Davidson motorcycle until 1929.
