NSU Delphin III - The NSU Delphin III was a streamliner motorcycle that set the motorcycle land speed record in 1956. Wilhelm Herz rode the machine to 211.4 miles per hour (340.2 km/h) at Bonneville Speedway in Utah to break 200 mph (320 km/h) for the first time. Its fairing designed in a wind tunnel at University of Stuttgart (then Stuttgart Technical College) gave it a drag coefficient of 0.19. The same engine powered Herz to a 1951 world speed record with a less efficient frame/fairing the Delphin I.
