Benelli GM engine 49cc (40 x 39mm)
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.
’70’s Benelli Gentleman (in NZ) with GK engine
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.

59cc horizontal cylinder 1-speed, automatic clutch
Benelli GK65 engine 59cc (44 x 39)
’70-72 Benelli Buzzer
’69-71 Benelli Hornet
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.
