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. Its creation is attributed to the American Berliner Motor Corporation. Models were produced in 250 cc through 450 cc displacements. The 450 variant was sold as the "Jupiter" in the United States. 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. 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. * Scrambler 125 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Desmodromic Valve
:''In general mechanical terms, the word ''desmodromic'' is used to refer to mechanisms that have different controls for their actuation in different directions.'' A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The valves in a typical four-stroke engine allow the air/fuel mixture into the cylinder at the beginning of the cycle and exhaust spent gases at the end of the cycle. In a conventional four-stroke engine, valves are opened by a cam and closed by return spring. An engine using desmodromic valves has two cams and two actuators, each for positive opening and closing without a return spring. Etymology The word comes from the Greek words ''desmos'' (, translated as "bond" or "knot") and ''dromos'' (, "track" or "way"). This denotes the major characteristic of the valves being continuously "bound" to the camshaft. Idea The common valve spring system is satisfactory f ...
