Myrons Mopeds

Benelli models with 4M, 4MS, 4M65 engines 1965-77

49 or 59cc 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.

The 4M engine was on the 1968-69 Benelli Dynamo Compact. M means marce, Italian for “march”, or in the motorcycle industry “foot-shift”.

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 Trail and Super Mini.

4M65 engine: Since 1970 the 4M and 4MS 49cc engine size was increased to an advertised 65cc on the 4M65. But the actually size was 59.3cc. Bore and stroke were 44 x 39 mm. That was dishonesty in labeling, motivated by “bigger is better” thinking.

The Benelli 4M65 engine is on 1971-73 Mini Enduro, 1970-72 Cougar, 1970-71 Dynamo Compact, Dynamo Trail (Scrambler), Woodsbike, 1972-73 Compact II, Dynamo II, Woods II, 1974-75 Dynamo Trail, 1976-77 Dynamo. It has large square head, larger piston, Dellorto ME15BS carburetor.

Benelli models with GM, GK engines 1965-73

49cc horizontal cylinder 1-speed, automatic clutch

 

 

 

 

 

 

 

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

 

 

 

 

 

 

 

 

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.

Benelli models with FA engines 1960?-75

49cc vertical cylinder 1-speed automatic clutch.

 

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.

The 1965-69 Wards Riverside 150D and 250D mopeds, the 1974-75 Benelli 3FA moped. and 1976 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.

 

 

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.

 

---

1965-67 Wards Riverside (Benelli FA engine)

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.

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.

This late 1960’s Minarelli P4  engine family was intended for racing or sport riding. 

P4 Racing changes: The crank changed from A24-32 (cone ∅13 pork chop flywheel) to A42-100 (cone ∅15 full circle flywheel). The width remained at 32mm. The piston changed from A24-31 (dome top 2.5 rings) to A42-102 (flat top L2.0 and 1.5 rings). The carburetor and exhaust got bigger.

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. 

 
1. ’71-72 P4S-70  69.9cc (45.0 x 44) on ’71-72 Indian (Italjet) SE74,

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.

Cosmopolitan Motors: Benelli mopeds and motorcycles were imported to the USA from about 1965 to 1988 by Cosmopolitan Motors in Hatboro PA. Cosmo sold the Automatic, Maverick, 3FA, Blazer, G2 and C2 pedal-start mopeds, and the 3VK kick-start moped. They also sold many different Benelli mini cycles and trail bikes, plus Benelli 250 twin, 250 and 500cc 4-cylinder, 750 and 900cc 6-cylinder sport motorcycles.

 

J.C. Penney: In the late 1960’s and early 70’s JC Penney department stores sold Benelli Buzzer, Dynamo, Hurricane, Volcano mini-cycles and Cougar trail bike in their auto centers.

 

Montgomery Ward: The Wards department store line was named “Riverside”. The earliest Wards Riverside models were scooters made by Japan’s Mitsubishi and Italy’s Bianchi companies, and mopeds made by France’s Motobecane. Those pre-1965 France-made Wards Riverside mopeds are completely different from the 1965-67 Benelli-made Wards Riverside mopeds.

 

Wards Riverside Benelli: In 1965, Wards changed manufacturers and opted to sell mostly machines from the Italian company Benelli. Benelli offered mopeds and a line of single cylinder motorcycles 50-360cc. The Benelli line plus a Lambretta scooter allowed Wards to compete in the marketplace with the Austrian Puch mopeds and motorcycles that Sears was selling under their Allstate brand.

By 1970 the moped and motorcycle sales went away for the department store retailers, and for European manufacturers in general, primarily due to the Japanese invasion with highly engineered, reliable and powerful 4 stroke motorcycles under the likes of Honda, Yamaha and Suzuki. Also, in 1970 the US Environmental Protection Agency (EPA) was created to oversee and combat increasing pollution and air quality issues. Smokey two stroke motorcycles and other high emission vehicles would be the first targets.
