Ducati on Wikipedia
Ducati Motor Holding S.p.A. is an Italian company that designs and manufactures motorcycles. Headquartered in Bologna, Italy, Ducati is owned by Audi through its Italian subsidiary Lamborghini.

Ducati is best known for high performance motorcycles characterized by large capacity four-stroke, 90° V-twin engines, featuring a desmodromic valve design. Ducati refers to this configuration as L-twin because one cylinder is vertical while the other is horizontal, making it look like a letter "L". 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 in consumer vehicles. 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 causes a loss of power that is likely when using a "passive" closing mechanism under the same conditions.

While most other manufacturers utilize wet clutches (with the spinning parts bathed in oil) Ducati previously used multiplate dry clutches in many of their 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 but the clutch plates can wear more rapidly. Ducati has converted to wet clutches across their current product lines.

Ducati also extensively uses the Trellis Steel Frame configuration, although Ducati's MotoGP project broke with this tradition by introducing a revolutionary carbon fibre frame for the Ducati Desmosedici GP9.

The next new Ducati engine to appear after the Ducati Apollo was the 90°V twin, initial Grand Prix racing versions being 500 cc, and the production bikes were 750 cc. There was also the Ducati 750 Imola Desmo that won at Imola in 1972. These engines had bevel gear shaft drive to the overhead camshaft, and were produced in round, square, and Mille crankcases. In the 1980s these gave way to the belt drive camshaft engines that have continued to this day, in air-cooled and liquid-cooled form. The Mille used a plain bearing crank, like the belt models.
