Ducati singles

The Ducati singles were single cylinder motorcycles, made by Ducati from 1950 to 1974. Chief Engineer Fabio Taglioni developed a desmodromic valve system in these years, a system that opens and closes the valves using the camshaft, without the need for valve springs. This valve system has become a trademark feature of Ducati motorcycles.

In 1926, the brothers Adriano and Marcello Ducati founded Societa Scientifica Radio Brevetti Ducati, a company in Bologna producing tubes, condensers and other radio components. On June 1, 1935, the cornerstone of a factory in Borgo Panigale was laid. By 1940, the company was engaged in the manufacture of electronic equipment for the military, making the factory a target for Allied bombing. The Ducati factory at Borgo Panigale was hit badly more than once, but maintained production.

During World War II, Aldo Farinelli, a lawyer from Turin, developed with SIATA a small engine to be mounted on a bicycle, called the Cucciolo ("little puppy") and in 1950 Ducati began producing its own complete 98-pound motorcycle with the same name.

From the mid-1950s through mid-1960s Ducati produced non-Taglioni-designed OHV singles with conventional pushrod valve operation, such as the 125 Bronco.

The market was moving though, towards bigger motorcycles and Ducati's IRI management felt diversification was the only answer. Ducati made an impression at the early 1952 Milan Show, introducing the Ducati 65 TS cycle and the Cruiser, the world's first four-stroke scooter. Despite being described as the most interesting new machine at the 1952 show, the Cruiser was not a great success. A couple of thousand were made over a two-year period before being withdrawn from production.

In 1953, management decided to split the operation into two separate entities, Ducati Meccanica SpA, and Ducati Elettronica SpA, under separate management. Dr. Giuseppe Montano took over as head of Ducati Meccanica SpA and the old Borgo Panigale factory was modernized, with government assistance.

By 1954, Ducati Meccanica SpA was producing 120 bikes a day, but cheap cars were entering the markets, and sales for many motorcycle manufacturers would decline.
