Minarelli Motor

Italy FlagMoto FBM (Fabbrica Bolognese Motocicli) 224 Via Battindarno, Bologna, Italy was founded 1951 by Vittorio Minarelli and Franco Morini, nephew of Alphonso Morini. The two young Italian engineers produced 125 to 250cc motorcycle engines for other makers. In 1954 the Pettirosso was born, a 50cc 2-stroke 2-speed cable-shift engine, destined to become the engine for most popular mopeds in Europe, and later the P3 3-speed version. Minarelli’s assistant Erio Testi helped develop those FBM moped engines, then later formed his own successful company. That is why Testi bikes all have Minarelli engines. See Misc Italian, scroll to Moto FBM. 

In 1956 the company split into F.B. Minarelli and Motori Franco Morini. See Morini Motor.

F.B.Minarelli (Fabbrica Bolognese Minarelli) 23 Via Melozzo da Forlì, Bologna, Italy was only four blocks away, formed in 1956 from the separation of Minarelli and Morini. The bike maker clients were divided equally in volume, Morini got Beta, Minarelli got the others.

From Wikipedia: In 1956 Minarelli switched to exclusively manufacturing two-stroke engines, in a 20,000 sq. ft. purpose-built factory. It employed 20 technical staff and produced 70 engines a day. These were sold to companies in Italy, other parts of Europe and South America.

Motori MinarelliIn 1967 the company changed its name from F.B. Minarelli to Motori Minarelli, and opened a new plant about 5 miles north, in Calderara di Reno. By the 1970s engine production had reached 250,000 units a year.

Minarelli successfully competed in Grand Prix motorcycle racing with Spanish rider Ángel Nieto winning 125cc world championships in 1979 and 1981.

In 1990 the company began a business relationship with Yamaha. Five years later it employed 350 people and engine production had reached 450,000 units a year.

In 2002, following changes in the world motorcycle market, Motori Minarelli became a member of the Yamaha Group.

By the late 1980’s, mopeds were out of style, and scooters were popular. Minarelli made 49cc two-stroke scooter engines with variators all through the 1990’s and most of the 2000’s. Minarelli has always been behind the scenes, making engines for “everybody”, but not advertising or taking much credit. Many people who own certain scooters don’t know their engine is made by humble and wise Minarelli.

Carabela Engine

Carabela with Minarelli V1 “d”

Carabela V1 (re-made in Mexico)

d. 1974-1979 Carabela Motomatic 49cc pedal or 60cc kickstart, Carabela Carerra (top tank)

These were made in Naucalpan Mexico, by Acer Mex S.A. under license from Minarelli. They have the left case for the bigger 94mm stator plate (earlier and harder to work on). They have metal fan covers. So this version “f” is a late 1970’s copy of a mid 1970’s V1 version “a”.

Carabela had two different cylinders, both with more fins. More later on what internals might be different …

 

 

 

V1 heads, left “round”, right “square”

Minarelli V1 Head and Kick versions:

a,b,c,d 1970-1980 had “round” head 5500, with pedals

Minarelli V1H

In 1986-87 Minarelli introduced the V1H, a V1 “c” with an improved cylinder, head, and no cooling fan. The cylinder was still piston port induction (where the intake manifold feeds the cylinder, and the bottom edge of the piston opens and closes off the port hole to make a net suction inward). The bigger uncoated aluminum cooling fins, cast over the cast iron cylinder core, carried plenty of heat away.

The problem with the V1 exposed cooling fan, was the fan blades would all break off, if the fan cover was struck with the engine running.

Minarelli V1L

In 1988-89, Minarelli introduced the V1L, a V1 “e” with a crankcase two-petal reed valve. The cylinder was still fan cooled, a V1 all cast iron type, but without any intake port, and a bigger bore, 40.3 instead of 38.8mm. This engine had “crankcase reed valve induction”, a modern design that made more torque, especially take-off. Morini already had success with it’s M1 reed motor eight years earlier, so Minarelli was several years late.

Minarelli V1HL

In 1988-90, Minarelli made the V1HL, a V1H with a reed valve and no cooling fan. The bore and stroke were the same 40.3 and 42.0.  The cylinder was a V1H type with cast iron core, black powder coated aluminum cooling fins, but without any intake port. The unused intake side of the cylinder wall has a shallow “boost port”. In conjunction with a window high up on the intake side of the piston, the boost port provides a third transfer path from below the piston to above. It is visible at the lower right in the above photo.

Also in 1987-90, Minarelli made the V1HLE (also called V1HL). It was a V1HL (case reed and no cooling fan) with an electric start mechanism, for use on trikes, which are difficult to pedal start. The Minarelli V1HLE electric start high torque one speed was used on late 1980’s Motomarina three wheeled mopeds. 

 

 

 

 

 

Myrons does not have parts for the models shown below, except things that are the same as V1.


2. Minarelli P1 1956-60 and 1963-66

This is where Minarelli began! The P1 was a pedal start, no kick lever. Unlike most Italian mopeds the pedal system was external, rather than inside the engine, with both pedal and motor chains on the left.

The 1950’s Minarelli P1 had a manual clutch. The 1960’s P1 was the same, except automatic clutch.

 


3. Minarelli P3 1956- 

This was a 3-speed hand-grip-shift with manual clutch. There were pedal and no-pedal versions. It had a bigger engine case than the P1, but still with the egg shape. There were two head versions, with a motor mount and without.

It is fan cooled with a very curvy rounded fan shroud. 

 

 

 

 

 

 

 

 


5. Minarelli EZ 1963?-68?

This was a one speed automatic with internal pedals. No fan or fan shroud. Some EZ parts are the same as V1.

The V2 mythical creature is real…

For some reason the Minarelli V2 is was not sold in California, or anywhere, other than this one model one year, a 1980 Testi Cricket V2. Other major makes offered automatic moped engines in both one and two speed versions, like Garelli, Puch, Peugeot, Motobecane, Morini. But Minarelli always offered only a one speed. 

Myrons does not have specific parts for Minarelli V2, other than those parts that are the same as on a V1.

7. Minarelli C2 1978-83

(49cc 2-speed automatic with pedals)

The C2 was on only a few deluxe US moped models.

Minarelli C2 specs

The C2 has the same all-iron cylinder, piston, “square” head, intake, carburetor, fan, and magneto as a “late” 1979-1985 V1. But the transmission and engine case is much different and longer. The bore is 38.8, not 38.7. The sprocket is 13T, not 11T.

Once again Minarelli made a two speed moped engine, but sales were less than they hoped for. The huge extra cost of the variator drive made it less affordable for most people. Morini had also made the M101, a two speed variator engine, and the MO2 two speed. But the Morini M1 reed valve one speed had better average acceleration than the Morini MO1 piston port two speed did, for a much lower cost and weight. By the late 1980’s, wise Minarelli gave up on two speeds, and “saw the light” of the one speed with case reed induction. 

Myrons does not have specific parts for Minarelli C2, other than those parts that are the same as on a V1.

 

 


8. Minarelli P4

The late 1960’s P4 is still kick only, still has the rounded case of the early 60’s, but the cooling fins are bigger and more square, and head fins are angled instead of straight.

In 1967 the company name and logo changed, from F.B. Minarelli to Motori Minarelli. Here they showed off their new logo by making it as big as possible, filling an entire page width.

 

 

 

 

 

 

 

 

8a. Minarelli P4E

The 1970’s P4E has a not-rounded engine case. It has many versions; 5 different cylinders and heads, 5 different kick levers, 8 different  magnetos, 3 different carburetors, and more.
