What a pretty little racer! Which manufacturer? Which engine? Which year of construction?
-
Experts can identify this beauty?
-
Or do the professionals?
-
German 2-stroke?
-
Yes!
-
Three-cylinder DKW?
-
No, sorry.
-
Then NSU? (bad eyes..thought to see one lying cylinder between two upright ones..)
-
Do you wear glasses? ;) As far as I know, NSU never built 2-stroke-racers.
-
Yes, you are right! I wear glasses, but have to put them on..
And again you are right: Stupidly I did forget to have a look at your previously answer..
Two more goals for you.. and I hope one for me:
MZ connection?
-
Sorry, I have to correct my statement on NSU racers:
In 1951 there was a short intermezzo with Lambretta 2-stroke scooters, converted for racing. One of the attemts for a new start in racing. First race in Dieburg was the first and only victory. Third race in Ingolstadt was a total failure and they withdrew the racing Lambretta.
Btw.: Winner in Ingolstadt was a certain Werner Haas on a self-tuned double-piston Puch...
Actually, I wanted to take pictures of the little racer, but maybe I can use them again...
But now back to the current puzzle: There is no MZ connection, except perhaps mutual theft with eyes...
-
Thanks for information about the NSU-2-stroke-racers. Didn't know about.
Is this an Adler racer?
-
Yes, it is! Locked for you, waiting for more details.
-
250 RS 1956 (thermosiphon watercooled with two small radiators air feeded by the small round holes In the front fairing)?
-
Adler RS 250 watercooled is nearly a bull's eye! But I have an earlier year of construction, the fairing makes the difference. Can you describe the difference?
-
It's the "Delphinverkleidung" ("dolphin-fairing") prior the "Vollverkleidung" ("full-enclosure-bodywork"), 1955
-
Here in comparison the difference shown on another example (NSU)
-
This is your next goal! A great piece of work. Yes, it is the 1955-version: watercooled with dolphin-fairing and duplex front-brake. Thanks for the comparison using the example of NSU Max. I particularly liked this: My first vehicle was a NSU Max and my best friend started at the same time with a Adler M 250. I'll show you the '55-model as a naked bike and a version from the beginning of 1956 with full fairing. I did not found any picture of this version in racing. In the late 50s, full fairing was banned, the motorbikes became very sensitive to side winds as a result.
-
Thanks for this very interesting puzzle! Never before, I saw a picture of the Adler 250 RS with "dolphin-fairing"!
The air-cooled version of the Adler 250RS-engine served as a base for Yamaha's later very successful 250-race-engines
-
Yes, it was fun to follow the development of the solution. The first series-produced Japanese two-stroke twins (Suzuki, Yamaha) have looked very, very similar to the Adler engines.

A look behind the scenes.
