Ducati Scrambler

The Ducati Scrambler was the brand name for a series of single cylinder scrambler motorcycles made by Ducati for the American market from 1962 until 1974.[1] Its creation is attributed to the American Berliner Motor Corporation.[2][3] Models were produced in 250 cc through 450 cc displacements. The 450 variant was sold as the "Jupiter" in the United States.[4]

The first Scramblers (1962-1967) were derived from street-legal models, and featured "narrow case" engines with lightly altered frames. It originally derived from a Ducati Diana road bike converted by Michael Berliner for dirt-track racing in America.[5] These Scrambler models all had a maximum engine capacity of 250cc, and are generally referred to as "narrow case Scrambler(s)"

  • Scrambler OHC 250 (1962-1963)
  • Scrambler 250 (1964-1968)
  • Scrambler 350 (1967-1968)

The second series used a wider engine case. Frames were modified with experience derived from Bruno Spaggiari's Ducati factory racing motorcycles.[6]
