It certainly did. On Oct. 16th., 1970, Cal Rayburn, in a single engine streamliner, powered by a modified Harley-Davidson Sportster engine, set the ULTIMATE AND SINGLE ENGINE motorcycle land speed record of 265.492 mph. The single engine record stood for over 20 years.
Many attempts by other motorcycle companies were unsuccessful. Even those with multi engine streamliners. Two, three, four engine Honda's, Kawasaki's, and Yamaha's could not better the Sporty for two decades.I don't know when the 2 record's were finally bettered and or by what. What's more, I don't care. For 20 years the Sporty was the "Best of the Best".
