In 1909, Harley had made a few examples (27 units[2]) of another v-twin, but the design was flawed and they did not try again until two years later.

Ignition was via a magneto, and the engine was started using bicycle-style pedals.

[1] Touting its effective muffler, Harley-Davidson advertised the 7D, and the other Harleys of this era, as "The Silent Gray Fellow."

The latter moniker was also in reference to William S. Harley, who was known for his quiet personality.

[4] A 1911 Model 7D from the George Pardo collection was set to be auctioned in January 2014.
