This fabulous 2-cylinder, 250cc, Rennmax NSU out 36hp @ 11000rpm dominated the sport in 1954. Werner Haas of Augsburg defended his world championship in superior style, by decisively winning the first four World Championship races on the silver Dolphin. The bike could go 131.4 mph, an astonishing feat for such small displacement. NSU had a 6-speed transmission, and weighed in at only 117 kg complete with fairing. NSU only built six of these bikes and were not-for-sale factory racers.
