Benelli FA

Benelli models with FA engines 1960?-75

1960's Benelli moped engine

’60’s Benelli FA engine

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.

This is an entire 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 1976 part numbers say the size in millimeters, here colored in orange.
