"Photographed here is Harry ""Otto"" Walker onboard a new factory works Harley-Davidson 11K series machine on the poplar boards at Speedway Park. The image comes from the F.A.M. American Championship 300 Mile race held September 12, 1915.  The scale and refinement of the Maywood track is evident in the background, it truly was a venue unlike any other before. Walker, who had recently won the big race in Venice as well as the 2nd annual Dodge City 300 set a new record for 100 miles with an average speed of just a hair under 90 mph, but his machine chewed up a valve on the 188th lap and was unable to finish. Out of the 27 riders entered Carl Goudy, onboard a big-valve Excelsior took home the $1,000 first prize, Indian's Teddy Carrol came in second, and Walker's Harley-Davidson teammates Ray Weishaar and Bill Brier placed fourth and fifth."
