2006 Ducati Paul Smart 1000LE

Ducati is best known for high performance motorcycles characterized by large capacity four-stroke, 90-degree L-twin[4] engines featuring a desmodromic valve design.[5] Modern Ducatis remain among the dominant performance motorcycles available today partly because of the Desmodromic valve design, which is nearing its 50th year of use. Desmodromic valves are closed with a separate, dedicated cam lobe and lifter instead of the conventional valve springs used in most internal combustion engines. This allows the cams to have a more radical profile, thus opening and closing the valves more quickly without the risk of valve-float which is likely when using a "passive" closing mechanisms under the same conditions.

While most other manufacturers utilize wet-clutches (with the spinning parts bathed in oil)[6] Ducati uses multiplate dry clutches in many of their current motorcycles. The dry clutch eliminates the power loss from oil viscosity drag on the engine even though the engagement may not be as smooth as the oil bath versions, and the clutch plates can wear more rapidly.

[edit] Product history

The chief designer of Ducati motorcycles from the 1950s was the late Fabio Taglioni (1920-2001). He designed most Ducatis during this period, ranging from the small single cylinder machines that were successful in the Italian 'street races' up to the large capacity twins of the 80s. Ducati introduced the Pantah in 1979; its engine was updated in the 1990s in the Ducati SuperSport (SS) series. All modern Ducati engines are derivatives of the Pantah, which uses a toothed belt to actuate the engine's valves. Taglioni used the prancing horse (identified with the Ferrari brand) on his Ducati motorbikes, Taglioni chose this emblem of courage and daring as a sign of respect and admiration for Francesco Baracca, a heroic World War I fighter pilot that died during an air raid in 1918[7] [8]

In 1973, Ducati also commemorated its 1972 win at the Imola 200 with the production model green frame Ducati 750 SuperSport.

(In 2006 the retro styled Ducati PaulSmart1000LE, which shares styling cues with the 1973 750 SuperSport (itself a production replica of Paul Smart's 1972 race winning 750 Imola Desmo) was released, as one of a SportClassic series representing the 750 GT, 750 Sport, and 750 SuperSport Ducati motorcycles.)

Ducati's liquid-cooled multi-valve V twins made from 1985 on are known as Quattrovalvole ("four-valve"). These include the 916 and 996, 999 and a few predecessors and derivatives.

[edit] 1990s

In 1993, Miguel Angel Galuzzi introduced the Ducati Monster[9] , a naked bike with exposed trellis and engine. Today the Monster accounts for almost half of the company's worldwide sales. The Monster, which has been out since 1994, has undergone the most changes of any motorcycle that Ducati has ever produced. After more than a decade of manufacturing, Ducati continues to create innovative changes to this classic motorcycle.

In 1995, the company introduced the Ducati 916 model designed by Massimo Tamburini, a water-cooled version that allowed for higher output levels and a striking new bodywork that featured aggressive lines, underseat exhausts, and a single-sided swingarm. Ducati has since ceased production of what many called the bike of the 1990s, supplanting it with the 749 and 999.
