I have been commissioned by a local non profit who had a bike donated to see if i can get it running. Upon getting the bike moved to my shop real quick i noticed from just some basic searches that its not what they where told. They were told it was a 1939 R75, which i know is not right. Im pretty sure nothing on the bike is even BMW, but some sort of R71 clone. Im just trying to figure out what it is for them, and then i also need a distributor, rotor and wires. Here are some pics of the bike and the numbers i have found on it.

  • Neck badge
  • left cylinder
  • right shock tower
  • left tranny case
  • right cylinder
  • under distributor

You can enter the

You can enter the engine/frame numbers into the boxes on the left side of the screen to see if things match up. I tried a few and it appears it's quite a hodge-podge of parts from various bikes. I don't know this era bikes very well, but it looks mostly BMW to me...again, just different models.

I'll take a shot. I'm afraid

I'll take a shot.

I'm afraid not much, if any, on this bike is BMW. The engine, carbs, and transmission are most definitely not BMW. I have questions on the frame, which lacks the tell-tale gussets on the Russian copies, but everything else to me looks un-BMW. My guess? Dnepr M72.

If you can get to it, Dietmar's website has a load of info on the R71's copies: http://histor.ws/bmwr71/01.php

Ooh-ooh! I wann'a play

Ooh-ooh! I wann'a play too!

My money's on it being a good ol' Chinese R71 repop. It certainly looks just like one I owned a few years back.

Bike ID

Dnepr (Russian) or CJ (Chinese) with a bunch of re-badged and transplanted metal. I know less about what the real BMW of this era looks like but the light on the sidecar fender and a few of the other tell-tale signs steer me to assume it's not really a BMW.
Of course I've been wrong before.

does anyone know of a good place to source parts for a knockoff? I need the carbon pins for the distributor but would much rather just get a new distributor and rotor.

I don't think the carbon

I don't think the carbon pickups are available separately. Contact Vech at Benchmark Works for parts on the west side of the Pond. All the ignition parts (except actual distributer bodies) for R5-R71 and clones are the same and I am sure he has them. Get a rotor, too. Not all rotors work with all caps.

You have a bitsa bike, probably created for re-enactments, that looks like a blend of Chinese and Russian parts. A fun toy in any case.

Good luck,

Bruce
