The addition of a motorcycle race at the Indianapolis Motor Speedway loosely coincided with the track's Centennial Era, which celebrated the 100th anniversary of the opening of the track (1909) and the 100th anniversary of the first 500 (1911). The motorcycle race represented a "throwback" to the early days of the Speedway, as motorcycle races were in fact the first competitive racing events held on the track in August 1909.
