Indian 1915 single 500cc 1 cyl ioe



Indian 1915   “Model E”    IOE 500 cc single speed   Racer    engine #  49G647 

Indian’s first, 38.61ci (633cc) v-twin appeared in 1907 with an engine clearly derived from that of the single, though mechanical inlet valves – introduced for 1908 – were an early improvement. 
The twin’s rear cylinder continued to form part of the frame until 1909 when a loop frame of the type favoured by rivals Harley-Davidson was adopted.
The Springfield Company’s first ‘Big Twin’ debuted that same year displacing 61 ci (988cc).
By 1913 Indian was the largest motorcycle manufacturer in the world; the 1913 production was  almost 32,000 machines. 
There were 2,000 dealers all over the world and  Indian controlled  some 42% of the  domestic  motorcycle market in the USA,  according to a company claim.
For 1915  some 10 models were offered. Most were twins, but the Model E was a single cylinder  which was available  in single speed, two speed and three speed versions.  
One of the  new features for 1915 was the use of   Chrome-Vanadium steel  tubing.  
This Model E single speeder has been restored in racing trim with racing handlebars, racing type saddle,  foot-controlled  clutch and Schebler carburettor. 
Output is some 7.5 HP.
