It was as a result of one of these wins, by a 283 cc single prototype in 1964, that the company decided to capitalise on the favourable publicity by introducing their top of the line sports machine, the 250 24 Horas (Hours) at the Barcelona Show the following year.

The bike differed from contemporary Ducati singles in several ways, the most fundamental being a change to a 69 x 66 mm bore and stroke from Ducati’s traditional 74 x 57.8 mm.
