Harley Davidson 1913 9E 1000cc 2 cyl ioe



Harley  Davidson  1913    “ 9E”    989 cc IOE V-twin  engine #  7502E

The first  V-twin Harley prototype  was  displayed at the Chicago Motorcycle Show in February 1907, but it wasn’t until 1909 that the first twins were for sale; officially they were still considered  prototypes and only 27 were sold.  
The engine had a capacity of 880 cc and had atmospheric intake valves. 
The standard colour of these machines was Renault Gray with carmine striping.    
The engines were not as good as the company expected so for 1910 no twins were offered and further development work was done. In 1911 a new engine was presented with 811 cc capacity and IOE configuration. 
This proved to be a sound design and it was developed further year after year. In 1912 a bigger, 989 cc engine was an option and in 1913 the 989 cc engine became standard. 
The 1913 machines were available with rear hub clutch  ( Model 9E) or two speed gear in the rear hub  ( Model 9F, available in prototype form only.).  
Top speed is  90 km/hour, tank capacity 9,1 litres, weight 140 kg.

This rare 1913 machine is an older restoration and is in very sound and original condition. 
It’s a splendid runner!
