Motorbike built in Modena by Vittorio Guerzoni, is presented in 1925. It has a 250 cc engine, obtained by coupling two cylinders of a 125 cc engine on a carter in which the gearbox is also locked. The crankshaft has 360 ° cranks, the gearbox is a three-speed, forced pump lubrication. The tourism version has an aluminum casing and reaches 80 km / h at a speed of 4000 rpm. The Mignon SS version has an elektron carter, reaching 129 km / h at 5500 rpm. The frame is very robust, with cradle, with front fork. In 1928, the release of a new single-cylinder 250 cc was announced, but it was no longer heard in the following years. In 1929, a 125 cc Turismo with opposed valve distribution, a 125-valve overhead valve and a two-cylinder 250 cc with opposing valve distribution and three-speed gearbox are on the list. The two-stroke engines are abandoned in favor of the four-stroke engines, even if the characteristics of the machines are unchanged. In 1932, the 500 cc, with an inclined forward cylinder and a four-speed four-speed gearbox, were very successful. They are made both with the overhead camshaft and two overhead camshafts. The control of the shafts is a chain enclosed in the crankcase.
