1. Minarelli V1 (1969-86)

Welcome. The Minarelli V1 engine is used on many mopeds, such as Cimatti, Gitane, Testi, Concord, Motron, Fantic, General, AMF, Baretta, Gadabout, Motomarina, and Safari. It is well made, performs good, and is easy to work on.

Minarelli V1H (1985-87)

The 1985-87 Minarelli V1H was a V1 with an aluminum cylinder, still with piston port intake. The cylinder and head fins were bigger. There was no fan. Everything else was the same as a “late” V1.

Minarelli V1 intakes look the same on the outside, but can have different inner sizes.

Minarelli V1 versions “a,b,c,d,e,f”:

 

 

 

Minarelli V1 Fan Cover versions:

a. 1970-1977 had metal fan cover 5430
metal fan base 5390, “early plastic” fan 5410.

b. 1977-1979 had plastic fan cover 5440
plastic fan base 5400, “early plastic” fan 5410.
Most of these are light grey, some are black.

c. 1979-1985 had “late plastic” cover 5445
“late plastic” base 5405, “late plastic” fan 5415.
All of these are black.

d. 1980-1986 also had “Fantic” cover 5445F
“Fantic” base 5405F, “late plastic” fan 5415.
All of these are black.

The individual pieces do not interchange.

 

 

 

 

Minarelli V1 Clutch Hub versions:

a. 1970-1977 had “stub plane” clutch assy 4930 and “stub plane” crankshaft 4410

b. 1978-1979 had “cone type” clutch assy 6180 and “cone type” crankshaft 4460

c. 1979-1990 had “cone type” clutch assy 6180 and “late cone” crankshaft 4465

 

 

 

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 …

 

 

 

Minarelli V1 Head and Kick versions:

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

e. 1980-1986 Fantic had “square” head 5505, with pedals

f. 1980-1986 Fantic had “square” head 5505, with kickstart

 

 

 

 

The “Fantic V1” engine version is from 1980 to 1986, shown at left. Square head, Fantic fan cover, late crank and clutch. Here we call it V1 “e” for pedal, or V1 “f” for kick.

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.

 

---

Minarelli V1HLE

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.
