Correct

The prewar R71s, which share their frames with the R66, R61 and R51 models, never have matching numbers. But the ones built in 1941 for the war effort, when BMW was no longer building those other models, did come from the factory with matching numbers.

Check out the R71 model information here on our site (you can get here by clicking on the BMW Models heading over on the left sidebar):
http://www.vintagebmw.org/v7/models?title=r71

You'll see that there are two serial number ranges for the frames and engines.

R71 Fraud

BMW made 3458 R71. I have probably seen more than that advertised on eBay in the last 10 years.

Because Russia and China made R71 clones for many years, most of the "R71" that are advertised are really Russian or Chinese bikes made to look like BMW. Most of the time the result is obvious, but some are very good forgeries. There are multiple sets of authentic stamps for engines and frames out there, so a "good" stamp is no guarantee.

Unless you really know what to look for, I would pass on any R71.

Early Russian M72 have become collectable in their own right and many re-enactors use Chinese Chang Jaings. Lots of people like to play with these old vintage looking bikes which is fine.......as long as they don't try to market them as authentic BMW "survivors".

In 2000 (before I had any idea of what I was doing), I bought a basketcase R71 from a fellow in Sweden based on a few poor photos. The engine, transmission and rear drive all have BMW casting numbers and the engine number appears to be an original stamp, so I am about as sure as I can be that it is legitimate. The frame has a correct looking stamp and none of the obvious Russian characteristics, so I think it is also legitimate. I got lucky, but I probably would not do it again.

In 2001 or so I met one of the more "notorious" USA vintage vendors at Veterama in Mannheim, Germany. We talked about R71 and his comment was, "Why do you want one? Even if it is real, no one will believe it." There is a lot of truth in that statement. Caveat Emptor!!

BMW R71 matching frame and engine number

I've just find this R71 with same motor end frame numbers. There is one of the last R71 models produced by BMW, and absolutely one of the last side valve engines produced by BMW.
Also I think that the low economic value of this model was affected by the copies produced in Russia
but the historical value of the original motorcycles is still very high.

Did you email BMW Archives

Did you email BMW Archives and ask about the delivery information on this number? I would do that and they will confirm if indeed the motor and frame left the factory together.
