DUCATI CUCCIOLO

noticeducati3.jpg

The first prototype Cucciolo, the T1, is a wonderful ‘collectors item’ but the design was flawed and it’s not very usable. The T2 – the 1950 model used here by Zwang – was the revised version manufactured by Ducati themselves and is a machine that can be ridden to its full potential. To quote the Ducati Museum:

In the middle of WWII a designer named Aldo Farinelli developed the prototype of an auxiliary motor to be mounted on a bicycle. Farinelli’s design had a number of major advantages over the competition, above all its four-stroke cycle and two-speed gearing, which used the engine’s power to its fullest potential. [This was later known as the T1]. Ducati, which up until that time had produced radios and electrical components, partnered with another Italian firm, SIATA, to produce the Cucciolo, or ‘Puppy.’ By 1946, the rights to Cucciolo production had become exclusively Ducati’s.

In 1948 Ducati came up with its first original design, the T2. It was heavily influenced by the T1 design, but made improvements in the engine’s efficiency, robustness, and, above all, logic of construction. The cylinder, for example, was redesigned and made removable and the drive mechanism made more accessible, the cylinder head was modified, and the rating was raised.

The T50 was mass-produced and is the most practical Cucciolo engine for regular use.
