1. Pedal models with G2-G or G2-R engine

G2 engine: (Gentlemen Due 49cc) is on US models 1977-80 Benelli G2, 1976-77 Benelli Blazer, 1978-80 Moto Guzzi, 1977-80 Moto Guzzi Robin and UK models 1974-80? G2. The G2 engine is the second generation of the late 60’s GM engine, a 25mph horizontal cylinder one-speed automatic, with a Dellorto 9mm sipping straw. Like the GM, the G2 engine does not have built-in pedals. The external pedal system is unusual with both pedal and motor chains on the left side. Most bicycle chains are on the right side, so a special reverse or “left hand” freewheel is required.

Dual left chain drive

PV controlsVeglia smallBenelli G2-US components: 2.25-16″ tires, 1.35-16″ rims, Benelli one speed automatic engine, Dellorto SHA 14/9 carburetor, #44 jet. Dansi 101813 magneto (external ignition ground type). CEV 2139 bullet head light, CEV 9400.2 tail light (with resistor for external ignition ground magneto), CEV plastic slide clamp-on switches, PV controls, Grimeca hubs (rear hub is special, has both chains on left side, Benelli only) and brakes, 11mm axles, Veglia speedometer with LH driver, 12×1 female gas valve with special long detachable handle-shaft that goes through a hole in the side panel, cables are all single-ended, seat post 25.0 x 22mm.

Benelli Bobo: The European version of the Blazer is called Bobo. It has Domino controls, different lights and electrical, and no speedometer.

PV controls

Benelli Blazer-US: The Benelli Blazer (Bobo) is made by Motobi. It is like a G2 but with a standard tube frame and separate gas tank. The Blazer version of the Bobo had the same parts catalog B1 to B4, except for the last page B5 that showed all of the changes. The controls (and start cable) changed from Domino to PV. A CEV 60mm speedometer, cable and driver were added. The CEV 2139 “bullet” headlight was round, bigger, brighter and required more watts. The CEV 9350 tail light also was bigger, brighter and required more watts. The 6V 21/5W #1154 bulb had a brake light and the lens had side reflectors. The switches were CEV round chrome clamp-on type, with English language labels. Right thumb operates engine stop. Left thumb operates lights and horn. The Blazer magneto generated more watts than the Bobo magneto.

2. Kick models with G2K-G or G2K-R engine

 

G2K engine: (Gentlemen Due Kick 49cc) is on 1970-76 Gentleman, UK models 1974-80? Motorella, 1978-80? G2 KS and G2 Elle. Eliminating the pedals and pedal chain simplified the frame design, and allowed the rear wheel to have a single sprocket and bigger wheel bearings (since they did not have to pass through the inside of a freewheel). 

Here is a English language 1978 Benelli Service Manual (UK models 50-125cc) a PDF download for the mopeds below and others. Euro models have a Dansi 101662 magneto. Euro models with brake light have Dansi 101813. US models (all with brake light) have Dansi 101441 or 101813.

How to tell if a Benelli Dynamo is 49 cc (4M or 4MS) or 59 cc (4M65). From left side photos, the carburetor is SHA14/12 or UA16-S on 49 cc and ME15BS on 59 cc. From disassembled engine parts, the case halves have part numbers in the casting inner side, or the piston size can be measured with a caliper.

 

1. US models with 4M or 4MS engine

49cc vertical cylinder 4-speed foot-shift, manual clutch.

 

4M engine: The 4M has a mild cylinder, with shorter and narrower ports, a 12mm ID intake, and a smaller 12mm Dellorto SHA 14/12 side-draft carburetor. It is limited to 1.5 horsepower to be operated in most countries or states without a drivers license. The 4M engine was on ’68-69 Benelli Dynamo Compact and ’76 Benelli Sprint. M means marce, Italian for “march”, or in the motorcycle industry “foot-shift”.

 
1. 4M engine with SHA 14-12 carb
2. ’68 Dynamo Compact, 4M engine
3. ’69 Dynamo Compact, 4M engine
4. ’76 Sprint (with pedals), 4M engine

4MS engine: The 4MS has a “sport” cylinder, with taller and wider ports, a 16mm ID intake, and a larger 16mm Dellorto UA16S down-draft carburetor. Horsepower 4.5 at 7800 rpm. This is the version shown in the parts illustration. The 4MS engine was on the ’65-68 Benelli Fireball, ’67-68 Fireball Trail, ’65-68 Riverside 450SS, and ’69 Dynamo Compact and Super Mini.

1. ’68-69 US Domino wrap throttle, thick black cables
2. ’69-71 US Domino slide throttle, thick grey cables
3. ’70’s Euro ?? slide throttle, thin black cables, grip shift

Note 1. Early 1970’s Domino controls were on US models. ’68-69 had wrap-type throttle with a thread-less-bottomed hole made for no adjuster. ’69-on had slide-type throttle also with no adjuster. The brake and clutch cables went into thread-less-bottomed holes made for no adjusters. The parts catalog shows and lists the cable adjusters #27 G7107/3D and #32 G7107/3E, but they are not in any internet photos.

Note 3. The brake and clutch cables on US models are thick, with 2mm inner wire and 6mm conduit with 7mm end caps. The clutch cable K61, with 6mm OD conduit, passes through a 6mm hole in the stop plate K30. The step ferrule (cable end) G364 adapts the 6mm OD cable conduit to stop at the 6mm ID cable hole. The same G364 step ferrule is on the upper end of the clutch cable, and on the rear brake cable for the same reason, to adapt a 6mm conduit to stop at a 6mm hole.

1. Benelli GM engine, 2. ’67 Gentleman, 3. ’65 Gentleman

 

GM engine (Gentlemen Monomarcia 49cc) is on the 1965-69 Benelli Gentlemen (Italy model), father of the Benelli G2. It is also on the 1969 Benelli Maverick (US model), a front-gas-tank version of the Gentlemen. Notice the 1967 spelling of Gentlemen, not Gentleman. The Gentlemen spelling appears in several late 60’s official publications. 1970 official brochures said Gentleman. See Benelli’s with G2, G2K engines. Here we will use Gentlemen for 1960’s and Gentleman for 1970’s. 

The GM engine has a Dansi MDP44 magneto and front-facing Dellorto SHA 14/9 carburetor. It does not have internal pedals. Instead both motor and pedal chains are on the left side, very unusual.

The Gentleman with pedals had a Domino left control with a start lever, instead of a left twist grip start control like the 1965-69 Wards Riverside had. It is visible in the photo. So it’s in bicycle mode all the time, until you pull the start lever.

GK (Gentlemen Kickstart 49cc) engines are on US-model mini-cycles. The kick models do not have pedals or a pedal chain.  The GK and GK-65 engines have a two-piece transmission cover, different than a GM one-piece. They do not have pedals or a pedal chain.

USA mini-cycles with GK and GK65 engines have Dansi ADP244S magnetos and front-facing carburetors, Dellorto SHA 14/12.

Benelli models with GK65 engines 1969-73

59cc horizontal cylinder 1-speed, automatic clutch


1. GK65 59cc (44 x 39), ’69-71 Hornet, ’70-72 Buzzer

 

GK65 engine: (Gentlemen Kickstart 59cc) engines are on 1970-73 US-model mini-cycles. The model names say “65” but the actual size was 59cc, not 65cc. The bore and stroke are 44 and 39 mm, so (44/2)*(44/2)*3.14*39/1000 = 59.27 cc. The GK and GK-65 engines have a two-piece transmission cover, different than a GM one-piece. They do not have pedals or a pedal chain.

These have Dansi ADP244S magnetos and front-facing carburetors, Dellorto SHA 14/12.

The ’65-67 Wards Riverside 150P, D and 250D (US), the ’74-75 Benelli 3FA (US) and the ’76 Benelli Export FA had FA engines. The left grip was a twist grip that operated the starting clutch. Normally the bike is in pedal mode. Twist the left grip back to engage the motor for starting. Once started it is under automatic clutch control, engaged above 10mph and in neutral below about 5mph. The hand levers are hand brakes, left rear and right front. The controls are early Domino. Throttle is a wrap-around type.

Mopeds with manual starting clutches usually have an extra hand lever below the left handlebar, for starting. Instead of a start lever, Benelli has a start grip. You pedal the bike, then twist the left grip, to engage the engine. Then let go once the engine has started.

Date: The date of manufacture is not stated on the ID plate or anywhere else on the frame. On 250D models with original speedometers, there may be a date stamped in ink, on the bottom of the speedometer shell. Remove the speedometer to see it.

Benelli FA Engine

FA engine (Frizone Automatico) engine had an upright slanted forward cylinder, not horizontal like the GM or G2 motor. It was rounded everywhere, not mostly square like the 1970’s motors. The pedals were part of the motor unit, not separate like on the G2.

1960's Benelli moped engine Wards Riverside cylinder and piston
1. ’60’s Benelli FA engine, 2. FA cylinder and piston, 3. 17x12x18 FA piston

The Benelli FA and M4 cylinders are the same as the Benelli M4S cylinder on the 50cc Fireball, except the porting. The Fireball cylinder has a 17mm (for the Dellorto UA16 carb) intake port at the flange, while the FA (and M4?) have a 10mm intake port hole (for a Dellorto 14/12 carb). The exhaust port is taller and wider on the Fireball. The transfer ports and intake port are also wider and maybe taller.

The 1960’s Benelli FA, M4 and M4S piston is the same as the 1970’s Benelli G and G2 piston. They are all 40.0mm bore, 39 stroke, and use the same rings 40 x 1.5 FG. The exhaust has a screw-on mount, with M34-1.5 male thread on the exhaust, female on the cylinder.

 

 

 

Parts List

Here is the 1965-67 Montgomery Ward Riverside Moped parts manual, condensed, colorized with prices, availability and specifications added. It is combined with a 1976 Benelli Export FA engine parts illustration and parts list. In ten years not much changed except the starting clutch and maybe something else.

On parts that have different sizes, the last digits of the 1976 part numbers say the size in millimeters, here colored in orange.

Minarelli C2 specs

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

1. 1963-67 Minarelli P4, P4S, P4SS

P4 has a 4-speed, foot-shift, manual clutch, kick start. All P4 crankshafts and cases have a width of 32mm between the bearings. P6 is wider, 36mm. Early P4 crankshafts have a 13mm right cone. In 1971 it became 15mm. 

P4S changes: The carburetor and intake changed from Dellorto SHA 14/12 to UA19S side-float type. The cylinder, piston and rings changed changed from 38.0 x 2.5 to 38.8 x 1.5. The compression ratio increased from 7.7 to 9.0. The head changed from small round fins M2-40 to bigger straight fins M24-12. The exhaust nut thread changed from M28 to M32. The nut goes over the pipe, so the pipe is smaller than that.

Top: 1965 Italjet Vampiro racer with P4 60 CA Cadetti (piston port induction) engine. The intake goes to the cylinder. The caption says “The Italjet Vampiro with Minarelli 60 engine presented in Monza shortly before the 1965 Milan Show. It will sell for 180 lire including the plastic fairing. Bore and stroke dimensions 41.4 x 44mm = 59.2cc. Note the built continuous double cradle frame and the four-shoe front brake.”

Bottom: 1967 Minarelli factory racer with P4 60 (rotary induction) engine. The intake goes to the crankcase. The caption says “The “lamellar” Minarelli prepared for the 1967 season has the same bore and stroke measurements as the conventionally fueled model, but delivers 9.5 HP at 10,800 rpm against the 9.0 at 10,800 rpm of the “first manner” Italjet which will also be referred to later. It comes from the “lamellar” propeller (rotary induction), with the 17 mm carburetor in direct communication with the crank arm. Always with 4% lubrication.”

In the 70’s and 80’s this engine was incorrectly referred to as a reed valve (lamellare) type, but it did not have a reed valve. Only 60 of these factory racers had this different intake system, according to moto gran premio e 50ini.  Instead of piston-controlled intake (induction), it had crankshaft-controlled (rotary valve) induction. That’s what Vespa Ciao had since 1968, and Yamaha had since 1961. The reed valve had not been invented yet. It was later invented by Yamaha and first produced in 1972. 

 

’66?-69? P4 60 QM (motor-car)
58.1cc (41.0 x 44) this also had that long stroke crank

 

 

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

 

 

3. 1967-70 Minarelli P4S, P4S-al, P4S-70

Late P4S changes: This ’67-73 late P4S is 95% the same as ’65-67 P4S. Only some kick start and gearshift parts are different. This is evident from the illustrations and part numbers.

5. ’72 Indian (Italjet) JC54 , SE54 and ’67-72 Italjet JC54, SE54, others

 

P4S-70 changes: The case, cylinder, piston and head changed for the bigger bore, from 38.8 to 45.0 mm. In 1971 the crankshaft changed from piston pin bushing type to a needle bearing type.

4. 1971-75 Minarelli P4V, P4V-70, P4V-75

Minarelli part numbers changed sometime around 1970.

P4V changes: The ’60’s rounded engine covers became angular, to fit the same rounded cases. In 1971 the crankshaft changed from axe (mannaia) shaped, also called pork chop shaped. The piston pin bushing 38.0005.0 changed to a needle bearing 38.0017.0.

Note 1. Indian Service Bulletin SVB-153: In March 1974 the flywheel key 2300.1024 changed  to 2301.1024, slightly shorter. That improved the seating (fit) of the flywheel, so it had less tendency of becoming loose and damaging the key and key groove.

Note 2: Indian Service Bulletin SVB-153: In March 1974 the pinion gear key 2110.1023 was eliminated. It is not needed as long as the pinion gear nut is tight. The key was on the ’67-70 P4S but was already eliminated on the ’71-75 P4V. That’s why there is only a 1960’s Minarelli part number for it.

Note 3. The genuine Dellorto SHA14/12 carburetor comes with a 52 jet, ∅18 sleeve, no air cover, no cable pipe. The F27 air cover is required for the correct air/fuel mixture. For a full parts list see Carb/Dellorto/SHA14.

P4V gears: P4V gears 1 to 4 had a 56 tooth total for each pair, 23+33, 27+29, 30+26, 33+23.

 

5. 1971-79 Minarelli P4E, P4E-al, P4A

P4E changes: The engine case changed from round to angular. The cylinder hole grew from ∅44 to ∅47. The cylinder studs grew from 40×40 to 48×48. This made room for bigger ports for more power, and made bigger bores 70 or 75cc possible, also for more power. The pork-chop all-needle-bearing P4V crankshaft became a full circle type. The exhaust bolts to the cylinder with a 3-bolt flange, instead of screwing on with a special inverted nut.

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.

History

 

 From https://it.wikipedia.org/wiki/FBM_(azienda)

FBMMoto F.B.M. (Fabbrica Bolognese Motocicli) 224 Via Battindarno, Bologna, Italy was founded in 1951 by Vittorio Minarelli and Franco Morini, nephew of Alphonso Morini. The company FBM (1951-1956) produced only motorcycle engines, two-stroke (2T) 50, 75, 100, 160 and four-stroke (4T) 100, 125, 160, 175 and 200 cc. 

 

Testi and Sachs helped Minarelli: Since 1933 Testi was a bicycle company owned by Umberto Testi. Umberto’s son Erio Testi worked in his fathers bicycle factory. In 1953 Umberto sent his son Erio Testi to Austria to visit Fichtel and Sachs, and learn about small two stroke engines. After Erio returned, he was hired by Moto FBM, and transferred the Sachs two stroke moped engine manufacturing knowledge to his friend Vittorio Minarelli. That’s why early 60’s Morini, Minarelli and Sachs pistons have the same dimensions.

 

 

Moto F.B.M.P-48: In 1954 the P-48 Pettirosso (red breast) 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.   

 

 

 

FBM split: In 1956 Moto FBM (Fabbrica Bolognese Motocicli) split into Fabbrica Bolognese Minarelli and Motori Morini Franco.

 

 

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 Minarelli: In 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.
