Morini Franco Motori S.p.A is a company based in Bolgna, Italy that designs and manufactures small engines for scooters, light motorcycles and mopeds.

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.

Engine Specs

The M01 and M1 engines have the same crank and flywheel. The M02 engine does not, however the stroke is the same. The M02 crank is longer on the clutch side to allow for an extra set of clutch and gears. The M01 and M02 are identical from the center split of the cases to the flywheel side. In fact, this can lead to confusion. Engine identification stamps are on the flywheel side center case. It is possible to have an M02 engine stamped M01, due to an apparent excess of M01 stamped cases being used for both applications during original assembly.
