A Brief History of the Marque
Made in Calderara di Reno, Bologna, Italy, 1974-83 and then in the nearby town of Kola Predosa.

Engines were mostly 50cc and 65cc Minarelli and Franco Morini, and in the 1980s the majority of models were for junior MX and trials.

Later the company partnered with Italjet, and in 2017 produced a variety of pitbikes and minimotos up to 150cc along with electric motorcycles.

The company website includes a short history of the marque: lem-motor.com

1976 Lem Chembol Raid, Franco Morini engine
1977 Lem Pizeta, Minarelli engine
1978 Lem Pratikal Kit, Minarelli engine
1985 LEM Type 820, moped.
1993 LEM 50cc LX3
1994-1997 LEM LX2, child's bike. S5-N engine, 2.50 x 8" tyres

Some models have a Franco Morini S5E engine.

Hi there,
I got your addy from cybermotorcycle.com. I hope you don't mind the query.
I purchased a brand new LEM LX2 back in the late 90's and it has broken piston rings. The cylinder appears to have ID of 40mm and piston OD of 39mm. There are three rings on the piston - one angled ring in the top groove, and two (thin and fat) in the bottom groove. Gudgeon pin looks to be 11mm.
Do you know where I could get a set of piston rings for this little bike? It would be a shame to throw it away after all these years.
Thanks in advance,
Gary One of the distributors listed on the company website, above, may be able to help.

Sheldon's, can you please tell me if an s6s cylinder will work on an s6 e ... Does the s model not have read valve or will it work? I believe I have the s6e with the reed valve block and my original cylinder is worn out.. need to either bore it or just pick up a cylinder and I see some suppliers have cylinders but I'm hard time finding the s6e cylinder and piston. Roy in Oroville California. It would seem that the s models are more also need some plastic.

Got this on a fair trade. Can not locate 2.50x 8" tires and unable to locate manual on this s5-N motor. Need to know factory spark plug. Has standard piston and bore. Replaced all gaskets (Top End) and proper fuel ratio. Runs good, still smokes A LOT with high grade 2 stoke oil 40:1.

Dear Sheldon's Please can you help me identify which Morini Franco 50cc engine this is. I bought the bike for my son, its a Lem 50, two-stroke , manual gears , kick-start goes backwards. The piston rings need replacing and I want to source the correct kit. Any help would be fantastic. Best wishes Cris

  • * "kick-start goes backwards" - conventional kickstarter on RHS of engine.

Thanks you so much for coming back to me, the Frame No:006445 Engine No: FMG30A42247. It would be marvellous if you could help identify which parts we need
many thanks

frame number
hello , I have a LEM mini motor bike which seems to be road legal but has never been registered for the road , im trying to make it road legal but I don't understand the frame number , which says ; LEM MOTOR MAX . then below it , *020372* then below it . DGM OL 89221 BBO , the name on the bike is lem small but I cant find any info on it any where on the net.

  • I believe *020372* is the frame number. Clear images of the machine along with pics of the frame number and engine number will assist identification.

Stops running after choke released
2003 Lem 50 LX1
Franco Morini engine S5E with Dellorto carb. Starts up and runs with choke on, as soon as you release choke engine stalls. I've cleaned, checked carb, gaskets, intake, etc. all seems ok. If I choke with my hand it tries to stay running. Please help! Thanks!

Ed: Common cause is lean mixture. This could be main bearing seals.
