 First shown December 1979, the Pantah came on the market as the 1980 500SL and the last of the line, the 650SL, was sold in 1986.Successful in racing as the 600 cc TT2 and later TT1 750 cc racer, the Pantah was a lighter, shorter wheelbase motorcycle, in a new trellis frame that was to become a trademark Ducati feature.When Ducati's 1976 350 cc and 500 cc parallel twins proved to be a marketing failure, Fabio Taglioni went to work developing the a replacement.
