This Day in Harley-Davidson History – Oct. 21, 1965 – George Roeder sets world speed record on the Sprint Streamliner with runs averaging nearly 177 mph.
In 1965, George Roeder piloted a streamlined Harley-Davidson 250cc Sprint and broke Class A and Class C world records at the Bonneville Salt Flats in Utah. He broke the record held by Stormy Mangham, who set a record of 156 miles per hour the previous year. Roeder achieved an average of 177 miles per hour. The vehicle that Roeder drove contained the 1966 engine that was still in the experimental stage. This record helped prove the engine’s power to the public.
