Mignon Motorcycles

A Brief History of the Marque


Built in Modena by Vittorio Guerzoni, the motorcycle was first revealed in 1925. It had a 248cc SV parallel twin engine which was created using two cylinders from a 125 on a common crankcase of unit construction with a 360 ° crankshaft, forced lubrication and a three-speed gearbox, housed in a cradle frame. The touring version had an aluminium crankcase and could achieve 80 km/h at 4000 rpm and the Mignon SS was good for 129 km/h at 5500 rpm.

In 1928 they announced a new 250cc single which did not enter production, but later that year they displayed a 250cc twin. 1929 saw the introduction of 125cc Turismo and Sport models (SV and OHV) and the 250cc twin, all with 3 speed gearboxes.

A 175cc OHV motoleggera was became a popular choice, suitable for daily commute and sports work.

The two-stroke engines were abandoned in favor of four-strokes, with the chassis and bodywork remaining the same.

1932 saw success on the racetrack using an inclined chain-driven DOHC four-speed engine with foot change. Their was an association with Enzo Ferrari's Modena factory during the development of these machines.
