Harley-Davidson V-Twin thunder will rattle the Springfield Mile grandstands when the AMA Pro Harley-Davidson GNC1 presented by Vance & Hines flat track racing series hits the historic dirt oval at the Illinois State Fairgrounds Sunday, May 24. The Harley-Davidson® Screamin’ Eagle® Factory Team with rider Brad Baker will make its first outing of the season at the traditional Memorial Day weekend event, joined on the track by fellow Harley-Davidson Screamin’ Eagle Wrecking Crew riders Jared Mees and Kenny Coolbeth, each piloting a Harley-Davidson® XR750 motorcycle.
