Russian 2-stroke

Congratulations for this fantastic site!!!

I found a lot of Information searched for al Long while. Im am Living in Germany and my English is very poor. Nevertheless I hope I can express what I like to tell. Im am in the process of researching the Story of a racing motorcycle developed an built in eastern Germany by former employees of the DKW race Department under top engineer August Prüßing between 1946 an 1948. After finished the work successfully four “GS350” and one “GS250” powered by supercharged opposite Piston engine were brought to Serpuchov includig extra engines, technical drawings an special tools. In Serpuchov several copies were built under the Name “GK1”. An engineer named Iwanitzki developed an modified supercharged opposite Piston engine with the cylinders as a converse “V” and built several racing motorcycles an small racecars with 350ccm. I could find many information, photos, technical drawings etc. an got in contact to People having been involved but it was not possible to find photos and other documents of the russion versions of the DKW racing technologie developed in Serpuchov an Photos showing recing impressions. The supercharged twostrokes also were used in world-record-cars as Zvezda 5 (1955) 0.245l two-cylinder engine, 50 hp at 7200 r/min. Transmission – 3, length – 3.2 m, the curb weight – 360 kg, speed – 200 km/h. Can you tell me a source or a person, site etc. where I can find documents and especially photos of the russian twostrokers.

Many thanks in Advance. Heiner Jakob

Dnepr/Ural “stubby” front fork

Hi Catwesel,

Note, he means B-Cozz community 😉

I have a Dnepr/Ural “stubby” front fork. It’s a nice piece of engineering but I don’t need it–my only Eastern motorcycle is a 1951 BMW-SAG R35/2 (EMW). Is there a classifieds section to your website? The fork is complete except for the upper triple-tree. It looks straight, and the headlight ears are nice. The rubber bump stops aren’t too hard. Is the steering tube supposed to be parallel to the fork legs? It’s not–it leans back a few degrees. I am in Baltimore, Maryland U.S.A.

Thanks, Paul
