Just to clean up a few Errors..

[QUOTE=gspell68;17429189]
2) Plus, ever notice that the KS-750's frame is one big piece of stamped steel and the R-75's frame is a bunch of bolt-joined sections?!?!? Welding technology was in it's infancy and the tubular steel frame was still not up to off-road rigors

Actually, the KS750 frame is mainly oval section tubes. The Headstock is made from two stampings welded () to give strength.

The R-71 was already obsolete during it's production and was the last flathead BMW ever designed!!! Olny about 3,500 were ever made.

The initial R75 prototypes were flat head. Its only because of the superior KS750 OHV design that BMW changed the configuration.

3) The KS-750 and R-75 weren't designed concurrently. Zundapp (who probably copied theirs from the Gnome & Rhone AX2 design or that other Belgian factory I can't remember right now) rolled out their rig well before BMW even had an R-75 assembly line.

The AX2 is a French design, the Belgian bike you are thinking of is the FN m1000. True, both BMW and Zundapp studied captured machines. But early drawings of what was the then known as the KS700 (with and engine based on the KS600) were already in progress by 1940.


The Germans wanted BMW to start producing the Zundapp design, but BMW insisted they could make their own version in a timely manner. The R-75 was the first motorcycle with hydraulic brakes.

Both R75 and KS750 deployed a cable operated front brake and chair and rear wheel hydraulic brakes by ATE

5) No post-war KS-750's or R-75's were made probably because the factories were destroyed and there were Allied enforced displacement restrictions on motorcycles. I read that there were about 100 civilian model R-75's made in 1948 from leftover parts, though.

Zundapp delivered approx 475 KS750 between 1945 and 1947.

Best

The fenders look like the first type used, and the rigid sidecar frame is also from very early on.

Not "valuable", but I wouldn't discount it so quickly, not many early or war era M72's here.

I could use the frame, should be easier to bolt up to my Zundapp than my Danish ACAP that was intended for a Nimbus flat stock frame.

Should anyone happen to do a recovery let me know..... have trailer will drive.

During WWII, Harley also produced the lesser-known XA model, designed for desert use. The government cancelled the contract after the war had moved out of North Africa, and the XA never saw action. Only about 1,110 were built and shipped.

Так много для моего мечтает о ценных "сарай найти" ... все я нашел, было навоза на сарае пол ...

I just picked this up after driving by it for months. The seller brought it back from Lithuania. 50's vintage M-72, either IMZ or KMZ. Same sidecar fender and leaf springs. Yours looks like a pretty original military rig by the look of the front fender and the frame loops over the sidecar fender. I think you passed up something with a little value. The M-72s were directly copied from the the R71s for the military, and the quality was much higher than subsequent Urals and Dneprs sold to civilians. As another inmate said, there's quite a following developing for these M72s. You can still get most of the parts you need to restore them, pretty reasonably. I could use that tranny in the pics! That sidecar frame and fender is worth something. So, where is it?

The bike is in So. Ca.
The owner isn't actively trying to sell it. I haven't been able to get him to name a price, other than someone supposedly offered him $2000.00 for it a couple years ago. That amount seems a little high to me. I would drag it home for $500.00 tops but I doubt he'd take that offer.
In a usable condition, what are these things worth?

the prices sem to be all over the place

......depending on level of completeness and originality. The have a big following in Europe but there's not many M72s over here. I paid under 2K and I'm told that was a pretty good deal. They're obviously not worth the same as a BMW, but a well sorted rig might fetch 7K. If you could get it for $500 you could easly recoup that in parts. Lots of hassle with shipping, etc. If you do buy it please PM me.....
