Harley Davidson, Crocker, Excelsior, Thor, Pierce Arrow, Indian, Sears, Reading, Flying Merkel, Henderson motorcycles and bicycles. Most are nearly a hundred years old and still running and riding. Legendary pieces of history and the forefathers of 2-wheeled racing events. It's only natural... if it has wheels and an engine... we HAVE to race it. Human 101. That's what we do!
