Neil Hodgson Ducati Puzzle

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.

In 1926 three brothers, Adriano, Marcello, and Bruno Ducati; founded Societa Scientifica Radio Brevetti Ducati in Bologna to produce vacuum tubes, condensers and other radio components, becoming successful enough by 1935 to construct a new factory in the Borgo Panigale area of the city. Production was maintained during World War II, despite the Ducati factory being a repeated target for Allied bombing.

Meanwhile, at the small Turinese firm SIATA (Societa Italiana per Applicazioni Tecniche Auto-Aviatorie), Aldo Farinelli began developing a small pushrod engine for mounting on bicycles. Barely a month after the official liberation of Italy in 1944, SIATA announced its intention to sell this engine, called the "Cucciolo" (Italian for "puppy," in reference to the distinctive exhaust sound) to the public. The first Cucciolos were available alone, to be mounted on standard bicycles, by the buyer; however, businessmen soon bought the little engines in quantity, and offered complete motorized-bicycle units for sale.

In 1950, after more than 200,000 Cucciolos had been sold, in collaboration with SIATA, the Ducati firm finally offered its own Cucciolo-based motorcycle. This first Ducati motorcycle was a 48 cc bike weighing 98 lb (44 kg) with a top speed of 40 mph (64 km/h) had a 15 mm carburetor giving just under 200 mpg-US (1.2 L/100 km; 240 mpg-imp).
