The MM (Mario Mazzetti) was an Italian motorcycle company located in Bologna that opened 1924 and closed in 1957.
Founded by Mario Mazzetti (1895-1964), a former employee of the GD, another motorcycle company based in Bologna, along with Alfonso Morini, Angelo Mattei and Joseph Massi-Deck. MM debuted in 1924 with a 125cc monocycle two times (with the engine patented by Mazzetti) with success because of the victories achieved in various competitions, including:
- Milan-Napoli 1925
- Italian Serie A Bicycle Motor 1926 and 1927
- Circuito del Lario 1927 and 1928
- Grand Prix of Nations 1927, 1928 and 1929
- Italian Serie A Speed Seniores 125 1928
In 1929 with it's growing success and in order to fall into a specific cc category , a 175 four-stroke engine was simplified and in accordance with the Code of the road allowed them an exemption from plate and license). With the abolition of the facilities in 1933, the 175cc was replaced by a 250cc. Both had some success, even in competitions the 175cc in 1933 conquered the world records in the mile run on miles, while the 250cc wining the Circuito del Lario 1938 and 1939 and the Milano-Taranto 1940).
In 1930 the 175cc to the 350cc was flanked on one side valves, motorcycles of traditional (with rigid frame and change by hand), but with very good quality and reliability (so it become the "official motorcycle" the Traffic police of Bologna). Minor success has made with the 500cc in 1934 and a decent success with the 350cc. Both, with the appropriate updates, would remain in the catalog until 1950.
1937 marked the abandonment of M.M. by Alfonso Morini. Its selling price was 25,000 pounds for some equipment and a motorcycle. Just the bike (turned into Motocarro) would mark the beginning of Morini as a manufacturer, which in the 1946 would bring him to open as Moto Morini.
The World War II heavily affected MM, which prompted them to take advantage of military orders, as many of the Italian motorcycle manufactures did, and because of hostility to the regime Fascist from Mazzetti.
Work resumed in 1947 with a 250cc Single equipped with a front suspension fork telescoping hydraulics (first example in Italy) and elastic frame. In 1950 a new 250cc alongside with a new 350cc derived from the quarter-liter were launched. The M.M. were among the most powerful bikes on the market in Italy: 250, 1953 declaring a maximum speed of 134km/h (equal to that of a "half" liter like the Gilera Saturno or Moto Guzzi Falcone, while the 350cc was clocking close to 150km/h.
The market had changed and was calling for more economical motorcycles and scooters, which range was not avaliable through MM. An attempt to respond to the demands of the market is the 125cc two days into 1954, but it is the to late. In 1957 MM declared the failure of the MM marque.
