The Sturgis Motorcycle Rally is the biggest gathering of bikers in the world, but it’s taken nearly nine decades to become what it is today. What would it have been like to travel to that very first rally in 1938? To find out, Zack and Ari climb aboard two 1930 American V-twins — a Harley Davidson Big Twin Flathead and an Indian Chief — and try to ride some 800 miles from Salt Lake City, Utah, to Sturgis, South Dakota. It’s an epic road trip that tests the boys’ stamina in nearly every way. Sturgis or bust!
