In 1948, one man broke a speed record wearing nothing but a bathing suit. Rollie Free needed two more miles an hour to break the American motorcycle speed record on his Vincent — so he stripped down to his swim trunks and laid flat across the tank at 150 miles an hour. The photo became the most famous image in motorcycling history. Footage credit for every clip is shown on-screen throughout this video.
