1. F.B.M. P48 1954-56

This had one speed, manual clutch with pedals. The design is based on a 1950’s Sachs moped engine. 


In 1956 Fabbrica Bolognese Motocicli split into F.B. Minarelli and Motori Franco Morini.

 



2. Minarelli E48 1956-57

This had a two-speed cable-shift, manual clutch. It is basically a P3 with one gear missing.

The new F.B. Minarelli logo was a triangle with wings. This was stamped or cast onto most of the engine parts. 1970’s and 80’s Motori Minarelli parts with this logo were originally on a 1960’s F.B. Minarelli model. 

 



3. Minarelli P3, P3-KS 1957-68? 

This was a 3-speed hand-grip-shift, manual clutch, with pedals or with kick start. There were two head versions, with a motor mount and without.

P3S changes: The bore increased from 38.0 to 38.8. So the cylinder and piston changed. The piston pin bushing changed to a needle bearing. So the crankshaft rod changed from bushing to bearing type. The small round head fins became large straight fins.
