I recently bought a moped of a young lad at work and i was wondering if anyone could answer a retarded question i have about this make of bike.

It's a PGO PMX 50cc sport .....is it 2 stroke or four stroke ?

the kid said he didint know and has barley used it, and never came with a manual or anything just the owner ship documents, its a W reg from 99/00 i think

i didnt really care when i bought it as he only wanted £200 for it but my old man was saying if i dont know i could f**k it up when refuleing

cheers in advance..............

Hi the speed they give is 30 MPH which is around 50kph...not sure where your getting the extra 15 mph from on yours...maybe when you going down hill :wink: probably de-restricted as the 30mph stated in the guide is restricted.

Dunno about the oil......someone will though :) Would guess u need 2 stroke oil for the engine....but dunno about mixing oil with the fuel :?

Found this...



- Two-stroke engines do not have valves, simplifying their construction.

- Two-stroke engines fire once every revolution (four-stroke engines fire once every other revolution). This gives two-stroke engines a significant power boost.

- Two-stroke engines are lighter, and cost less to manufacture.

- Two-stroke engines have the potential for about twice the power in the same size because there are twice as many power strokes per revolution.


- Two-stroke engines don't live as long as four-stroke engines. The lack of a dedicated lubrication system means that the parts of a two-stroke engine wear-out faster. Two-stroke engines require a mix of oil in with the gas to lubricate the crankshaft, connecting rod and cylinder walls.

- Two-stroke oil can be expensive. Mixing ratio is about 4 ounces per gallon of gas: burning about a gallon of oil every 1,000 miles.

- Two-stroke engines do not use fuel efficiently, yielding fewer miles per gallon.

- Two-stroke engines produce more pollution.


-- The combustion of the oil in the gas. The oil makes all two-stroke engines smoky to some extent, and a badly worn two-stroke engine can emit more oily smoke.

-- Each time a new mix of air/fuel is loaded into the combustion chamber, part of it leaks out through the exhaust port.
