MO Info

It’s hard to find info about these. Like other Morini and Minarelli engines, the engine identity is concealed or replaced with the bike maker name. The bike maker flyers are the best source of official photos and information.

The first horizontal-cylinder Morini one-speed moped engines were on the 1968 Malaguti Dribbling.

1968 Morini MO Malaguti horiz. cylinder
49.0 cc (40.0 x 39.0) 1-speed automatic, 7.5 cr
early aluminum cylinder steel sleeve 40.0
normal version 1.4 hp. 40 km/h, 14/12 carb

 

early aluminum cylinder: The late 60’s and early 70’s horizontal aluminum cylinders with all-horizontal fins, have a standard bore of 40.0 mm. 

iron cylinder: These horizontal cylinders are cast iron, darker, heavier, with top and bottom fins vertical and side fins horizontal. From the front view, the fins resemble a very thick plus sign. They replaced the early-aluminum cylinder in the early 70’s. They have a 40.4 bore. 

aluminum cylinder: These horizontal iron sleeve aluminum cylinders had bigger fins, thicker plus sign style. They were made from the early 1970’s to about 1980. They have a 40.4 bore.

Gyromat: In about 1969 a new series of engines began, called Gyromat. These were pedal-start horizontal-cylinder one-speed automatic clutch Franco Morini moped engines.

Convert: In the mid-1970’s Morini developed a two-speed automatic version of the Gyromat, called the Convert. A Morini Convert is the precursor of the Morini MO-2.

Gyrokick: In the mid-1970’s Morini produced a kick-start version of the Gyromat, called the Gyrokick.
