The Second World War was extremely hard on Ducati: the Borgo Panigale factories were razed to the ground in 1944. Fortunately, the Ducati brothers spent the duration of the war studying and planning new products to be introduced to world markets at the end of the conflict.
In1946, the Cucciolo appeared: the small auxiliary motor for bicycles destined to become the most famous in the world. First sold in an assembly box to be attached to the bicycle, it soon acquired a frame of its own, which was constructed by Caproni in Trento (another famous brand in the aeronautical field) and based on a Capellino patent.
In a short time, the Cucciolo became a real miniature motorcycle.
Thank to the Cucciolo's success, and that of its descendants, Ducati became an affirmed trademark in the mechanical sector.
