A Brief History of the Marque
1919-1945 J.S. Rasmussen (DKW) und Auto Union AG, Zschopau
1949-1958 Auto Union AG, Ingolstadt und Dusseldorf
1958-1966 Zweirad Union AG, Nurernberg
Jorge Rasmussen founded Motorenwerke Rasmussen in Zschopau, Germany in 1906, and entered the motorcycle industry with a 30cc bicycle motor in 1921 and shortly thereafter introduced 122cc Golem and 142cc Lomos scooters.
The name DKW was trademarked in 1922 and the firm went on to become one of the largest manufacturers of motorcycles in the world. By 1928 they were building some 65,000 engine units annually, and DKW engines could be found powering some 60 German marques of the interwar period.
DKW bought out the ailing Audi company in 1930 and the similarly afflicted Horch in 1932. The Horch acquisition was made in conjunction with the wealthy Wanderer marque. As the senior partner, Wanderer appointed Baron Klaus von Ouertzen as managing director.
Rasmussen was forced out of the company in 1934, and von Ouertzen fled the Nazis for South Africa in 1935.
The company was further restructured after the war, joining Victoria and Express in 1958 to form Zweirad-Union, which in turn was absorbed by Fichtel & Sachs in 1966.
DKW motorcycles employed mostly two-stroke engines and often were technically advanced.
The French Manurhin was a version of the DKW Hobby scooter.

I recently found a picture of my grandfather (seated back) on a German motorcycle during WWII. I have researched the subject, and have found that it is definitely a DKW German motorcycle. I have contacted several museums throughout Europe, and some have emailed back with varying opinions, but no one has been able to identify this motorcycle for certain. Just wondering if you might have some insight. I am doing research on my grandfather and especially his time spent in WWII, and fitting this piece to the puzzle would be cool. Plus, my boys and I are actually thinking of trying to track down a model that is similar for purchase, even if we have to travel to Europe to get it! Thank you for your time.

DKW / Hercules Enduro 125
Have just acquired what I assumed to be a restored DKW Enduro – recently imported from California – believe it was built somewhere between 1969 & 1972. The engine # is: 9015368 and frame # on the headstock is 427004170. One German DKW club that I contacted said it wasn't a DKW but possibly could have been manufactured by Zweirad-Union. Another source said that in all probability it is a DKW Hercules K125GS imported into the US between 1970-71 with a Sachs 5 speed engine & DKW ignition. On that basis I am now trying to source some DKW / Hercules / Sachs badges or decals appropriate to the model. Any assistance you can offer would be most appreciated.

Re questions and the pictured DKW-twinport-rigid on this address: DKW gallery
This is an NZ 250cc (or maybe 350cc), built somewhere between 1937 and 1939.

SACHS was the largest manufacturer of two-stroke motorcycle engines over here in the fifties, sixties and seventies. These engines were used by many motorcycle manufacturers, Hercules being the most important of them.
HERCULES belongs to the SACHS group and the HERCULES bikes were
sold under the SACHS or DKW brand in some foreign countries. Nothing interesting
to know about SACHS and HERCULES, just plain-Jane mass-production two-stroke
motorcycles. The only interesting bike HERCULES ever built was the W 2000,
which was sold in other countries as the DKW W 2000, which was the first
production bike with a 27HP SACHS rotary engine. I'll scan and send a picture
of it as soon as I have found one.
