A Brief History of the Marque

Suhl is located in the southern part of the former East Germany. In the early 1920s the Simson company manufactured also large and luxurious automobiles, bicycles and weapons.

After the second war the Russians took control and formed "Awto Welo", better known as AWO.

From 1952 to 1962 they produced the AWO 425 T model, a single cylinder 250 cc, 12 hp, four stroke, shaft drive touring model. The 425 T is very similar to the BMW R 26 of the same period.

This was followed by the AWO 425 S (also marketed as the SIMSON 425 Sport), a single cylinder 250 cc of 15.5 hp, four stroke, shaft drive with better suspension and handling. In competition it was woefully outclassed by its West German counterparts from Adler, NSU and DKW.

Production of the 250cc AWO models was curtailed around 1963 in favour of two-stroke MZ models.

SIMSON Suhl was also very well known for 50 cc auto-cycles, many having the names of birds.

There are fan-clubs for these models. Look for the names "Schwalbe" or "Star" - they were produced in huge numbers until the collapse of the Soviet Union.

AWO was part of the IFA concern.

1954-1960 AWO 425 T 247 cc single cyl. (68 x 68 mm), 4-stroke 12 h.p. @ 5,500 rpm
1955-1961 AWO 425 S 247 cc single cyl. (68 x 68 mm), 4-stroke 14 h.p. @ 6,300 rpm (later 15½ h.p.)

The bike is an 250cc brand AWO 425 Touring. build in DDR (east Germany) in 1955.
I do hope this is information enough for dealers or for enthusiast that might have a spare front seat feather to this bike.

AWO 425

I have an engine, trans & final drive from an 425. The # is 168724. Any idea when it was made, and if someone would be interested in buying spare parts? Thanks!
BTW, the final drive's number is: 169065 S.
The engine/trans does not turn over, the fd is stuck as well, but I will try to free them ever so gently(I've resurrected some /2 BMW's). From the outside I can see that there are no pushrods or valve cover. Also have a headlight bucket with speedometer, cable and wiring. It has had a sealed beam roughly installed.
The final drive and transmission both turn freely, now. The hand shifter seems to give me 4 gears, what is the shift sequence? Got no new seals or bearings to install, and I'm sure that after this many years they will leak without new gaskets and seals.
I think the parts are from a 1957 AWO 425 S.
Piston rings are still stuck to the cylinder. Magneto and generator were under the front cover, and appear intact ( I'll get after them with my ohm meter soon).
One of the rocker arms is stiff, and I've yet to check out the valves/head condition. Head is off and looks nice as far as- no bent fins or damaged sealing surfaces.
I'm just hoping to find someone that needs these parts to keep their ride on the road.

AWO 425
I own a AWO 425 1956 in all original condition, paint in excellent condition and running order. I bought from a gentleman in eastern Germany in the 1989. It has been garaged and all original. I has a extra seat for the rear fender

I would like to sell it. I am located in California....Any offers please...My cell phone is 661 312 5967 and my name is Gregory Berg.

I will have to scan photos at work tomorrow to insert. I have all the original documents, manuals as it was a police bike DDR

Attached are photos of bike in original form and also documents I received
with bike including a small blue AWO 425 manual book ( not shown )  The bike
runs perfect, just was serviced, valves and carb adjusted, new german tires,
seals, speedo cable

In your opinion , what do think the bike would bring in US Dollars???

Best regards,
