The last of the racing versions of the 125 cc Sprint, the 1958 version with which the rider Ricardo Quintanilla participated in the Spanish GP in Montjuïc, this unit developed 18 HP at 11,000 rpm and, until it broke down, was ahead of Carlo Ubbiali’s MV. It has a Dell'Orto SS 30 carburettor, 124.5 cc displacement with dimensions of 51.5 x 60mm and a six-speed gearbox.
