A Brief History of the Marque

Suhl is located in the southern part of the former East Germany.

Simson was the largest East German moped manufacturer. Today they are a lot smaller, but still exist - see

They began production in 1948 with a well made 250cc four stroke called AWO 425.

By 1960 this bike was too expensive to make, compared to the MZ, so the communist government ordered them to make mopeds. They made models like the simple SR1 and SR2, sports models like Sperber and S51 and the million-seller scooterlike Schwalbe.

In the 60's they were among the most modern mopeds, but in 1990, the year of reunification, they only had old models. Their glory days were in enduro and Sixdays events where they won everything one could win, including World Championship.

The 1990 winning 80cc bike featured rotary disc inlet and 29HP.

Simson engines were also used in road racing. I own two of those : a 1966 8-speed 50cc and a 1972 rotary inlet 6 speed watercooled 50cc with 16,5 HP.

Before the war Simson was a sporting gun maker located in Suhl, owned by 3 brothers of Jewish descent. The factory was expropriated by the Nazi's and re-located to a concentration camp to make guns for the German army. After the war the Russians took the factory and made small motorcycles. The 3 brothers managed to escape to the U.S.A

Simson Schwalbe KR 51/1
Hi, I would like to sell my old Simson Schwalbe KR 51/1, built in 1965.Everything is complete, the original papers and handbook are also there. I didn´t drive her for a long time, so the carburetor might need some cleaning, battery and oil might have to be changed.
Do you have an idea, where I could sell my Schwalbe?
Thank you very much for an answer,
best regards from

May 10th 2009

Now I made an older Simson logo. It's was on Simson Schwalbe. My father had a Schwalbe, and he was a happy owner. Theese bikes older series was good, because there was a cooler ventilator under the cover.
When I was young, I had an N50 type modell. It was good and popular, but the modified SB51 was better.
If you need, I will send my bikes photo to you.
Do you need a moderner Sheldon's emu logo?

1959 moped
1959 simson sr2 moped
I have recently purchased a 1959 simson sr2 moped in incredible condition
the paint is very good with all origanal emblems from tires to the seat to the origanal air pump stored for 40 years in a garage.
It tooks several hours to carfully clean and detail the moped thus having
40 years of dust on it, after cleaning it,to our amazement every thing is in perfect working order . The colour looks like a military tan .
could you please help me with some information on the history and the current value of this moped
many thanks Gus

Hello Sheldon,
Sorry to bother you but I found your site while looking for info on Simson and wondered if you might be able to help me out. I have a 125 supermotard that was shipped right before they went out of business and I am looking for someone that might know how many were made, if parts are available etc... do you have any contacts, links or know anyone that may know about these bikes?
