Demm Motorcycles

Made in Milano, Italy
from 1953 to 1982 or c1988.(1)

A Brief History of the Marque
Italian two-strokes and four-strokes made in Milan from around 1953. Their engines were sold to a variety of other manufacturers including Legnano and Testi, particularly the 49cc twostrokes.

In the mid fifties Demm produced a 49cc model called a 'Dik Dik' (or Dick Dick). The engine was model '3M'. In the UK at this time there was a chap called Bert Fruin who built his own motorcycles and he used this engine in his machines. He built a motorcycle called the "Fruin Dartella". These bikes raced in the Isle of Man TT and at many other UK circuits. The bike also achieved a speed record of 89mph.

I bought a Demm cyclomotore. Can you please tell me what type this is?
I think its a Dick -Dick with a rare TESTI tubolare frame. Build in 1956...Is that correct?
Best regards,
Arjen Reumer Holland

    Have found no further information on this machine - it does however resemble one or two later models. Ed.

Missing a Pedal
Demm Scout Moped
Hi, I have a Demm Scout. I'm not 100 % on the year, but I think It may be either a 1977 or 1978.
One of the pedals is missing. Does anyone know if I can use a regular bicycle pedal or am I out of luck? I know parts are very hard to find. Thank you, Liana

... Anyway I didn't know that you were actually associated with Sheldon'emu when I sent the photos to you so I should explain a bit. I have a 1957 50cc Legnano motorcycle with a Demm engine that pops out of gear. While researching places to visit before traveling to Bologna I stumbled upon reference to the Demm Museum, not too far from Bologna. After much correspondence I finally got in to the museum. Once there they were very gracious and generous with their time. In fact they opened the museum for us and we (wife and I)were given a tour by the founder of the museum, the son of the man who built and designed Demm motorcycles. That man, the father, is Giuliano Mazzini. He is the man on the right in the photo and that's me on the left. He came by and gave me a talk on gearbox design and remedies. I could go on, this is the short version of a long story.

Something I learned is that although there are many small museums and collections of cars and motorcycle in Italy supposedly open to the public, not that many really are. I think it may have something to do with tax status. So plan accordingly, you may find the museum that you want to visit is only open to the public one day in a year (seriously). That being said if you are a group or have a compelling case you might get a special tour if you arrange beforehand. Check out

I have some other motorcycle photos taken on the same trip at another museum and at a vintage motorcycle race I will try to make some kind of file and link.

Dear sir/ madam,

Last week I bought a nice moped called a Demm Ping Pong. Unfortunately it's hard to find any information about this moped. For example, it seems impossible to find out in what year the moped was build. To insure the moped I need more information than I have at the moment. Can you help me or do you maybe have some suggestions? Thanks in advance!! Timmermans Rufus

The first seat of demm (daldi e matteucci s.p.a.) is going to be demolished (pulled down)because property is going to build a new building! It would be a pity because the present structure (besides the historic value of being the first seat of demm) was built at the beginning of 20th century !

i bought a1976 demm smily moped and its clutches are dry rotted do you know where i can purchase them? thanx paul

April 15, 2002
I found you site and want to give you some information about DEMM. It is an Italian company still "alive" and was well known in Italy until the end of the 80s. Anyway in Italy you can find spares for most of the motorcycle and moped and if you want to find one you can always go in a junkyard and you will find many sometimes still working. I have 2 moped and 2 motorcycles my parents bought at the end of the 60s are still working and I never had any problem to find spares (Well I have to say that I live in Itali 100 miles form the factory that made them). Anyway if you are really interested in DEMM think about a tour in Italy!!! If you are interested in some photos and a copy of a manual for a moped let me know.

Hi, I'm Mike from Minnesota. I picked up a 1977 Demm Smily 50cc a few months ago from a guy who had it sitting in the back of his garage for 20 years. It looks in good shape with only 245 miles. He said he won it in a raffle in '77 and has no information for it. I want to tune it up and need info about how to go about it. What oil do I put in the crankcase? What adjustments should I make? What is the proper gas/oil mixture for the engine? Any info or suggestions for tuning it up, or just general info on it would be greatly appreciated. Thanks. -- Mike Prieve -- mprieve at

Hey! I was wondering what you think this is worth: A 1976 Demm Smily Moped, imported from Italy (currently in USA). It is in excellent condition with only 1230 miles on the odometer. All original parts. It starts with ease and runs perfectly! It has been mostly in a house for the past decade. Only the paint needs minor attention. If you wish you can see it at (geocties). Thanks for your advice! If you are looking for parts call Curtis at 757-463-4985. He is an aftermarket parts dealer and can find Demm Smily parts. -- Mark Padgett -- gitbass at
