1973 250 cc 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, and with the production of the new Ducati Scrambler in 2015.[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]

A new Ducati Scrambler was introduced at the 2014 Intermot motorcycle show, with plans for sales to begin in early 2015.

Production history[edit]

Production history: Grizzi and Perelli[5]

The first Scramblers (1962~1967) were derived from road going 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.[6] These Scrambler models all had a maximum engine capacity of 250cc, and are generally referred to as "narrow case Scrambler(s)"

"In the 1965s-'60s Joe Berliner was far and away the best of Ducati's customers," states Livio Lodi, "and so he had the power to influence the firms policies. He encouraged the project of an all-purpose bike that would appeal to young people but also revive the youth of the not-so-young. Remember that in those years in Europe and above all in Italy, the utilitarie like the new Fiat 500 penalized sales of motorbikes with medium-large engines. Berliner knew that in the states cars would never affect motorcycles sales, the two market segments were nurtured by completely different dreams..."
