Company History
Established in 1954 by Franco Morini, the company was the result of a split in the business partnership between Morini, and Vittorio Minarelli. Vittorio Minarelli and Franco Morini set up a factory together in 1950 called "FBM (Fabricca Bolognese Motocicli SrL)" to produce motorcycle and moped engines. They then parted ways and each founded their own engine production companies; Vittorio Minarelli formed "Minarelli" and Franco Morini formed "Morini Franco Motori".
Engines
Currently, Morini Franco Motori produces 50cc air- and liquid-cooled two-stroke engines, 125cc air-cooled four-stroke engines, and 400cc liquid-cooled four-stroke engines. The most common Morini engines used on mopeds are:
- M1 case inducted single speed
- MO1 piston ported single speed, and
- MO2 piston ported 2 speed
These engines are bomb proof and a fine piece of Italian wonder. Kits for these motors are rare but can be found; you just have to do some searching.
