Harley  Davidson  1915    “11F”   989 cc IOE V-twin   frame # AL 4179    engine # 9517K

The year 1915 was unique in the history of Harley-Davidson. For the first time a three speed countershaft gearbox was fitted and the  engine power output grew from 9 HP @ 2400 rpm to 11HP @ 3000 rpm. 
To accommodate the larger dimensions of the new adjustable valves the engineers had to cut notches in the lower edge of the fuel tank, an identifying feature displayed on the Model 11 we can offer here.
The 1915 Harley-Davidson was, thanks to the new transmission, edging towards a completely modern state of development yet this was the final year of the antique flat tank design before the introduction of  the new streamlined appearance for the 1916 model year. 
The finish was still their familiar Renault Gray with broad dark gray striping and name Harley-Davidson in red with gold lining.
This nicely presented example has formed part of a private collection for a number of years and was displayed in the Stanford Hall museum. It is offered with the benefit of the attached, period sprung sidecar  and is fitted with acetylene lighting system and Cowey speedometer.
A very informative  description and road test of this combination written   by “Titch” Allen was published in  “The Second Vintage Roadtest Journal” on pages 28-31.
