I got this about 3 weeks ago, I`ve known about it for about 20 years. The engine is a CT1 with no numbers. I put new seals in it, everything looked great. The bore was on 2nd over and looked fine. It`s ready to start. Any guesses on the frame, it looks to be made for a Yamaha.

Tank might be the give away ...

How about an early 70's DKW 125. They had Sachs engines, or at least the ones sold locally had Sachs engines and leading link front suspensions.

Maybe a Roehr-Van Tech creation/prototype/one-off?

Looks a little similar, yet different.

But with your experience you'd know if it was a Roehr.

Took this vintage MX photo at Red Bud in Buchanan Michigan a couple years ago. Looks similar. Is this a DKW?

Yes, that is a DKW. A local guy here in the Daytona area sold them and they were popular. I recall them as being very fast. I think you have a DKW frame. Cool bike.

You may be on to something, I`ve heard about a prototype and it finally landed in my lap but I need concrete evidence. There is some denial but they haven`t seen it yet. I have some provenance we will see when I show up at Hanford with it.

Started right up and everything works. Gearbox, clutch all work fine, carb is leaking and the kickstart isn`t returning like it should. Not bad for a 40 year sleep.
