    There is a 1965 Dnepr MB-750M for sale locally and I am wondering what these go for now days. It's supposedly had a complete restoration including paint and an engine re-build. Comes with tools and a manual, gas can, ammo can, machine gun mount.

    By the pictures it looks to be in great shape, though I know you can't tell by looking at pictures. What is a good ball park price for something like this? Also how easy is it to get parts? Not that it's that big a deal but do these get fairly decent gas mileage? The guy is asking $6,500obo.

    Another thing...has anyone ever swapped out engines with a BMW power plant for reliability. If my memory serves me correctly these engines are not known for their longevity because of poor tolerances from the factory. Hopefully that will have been taken care of with the rebuild. Are newer model year parts interchangeable with a "65" model?
    Any other things I should know or look for if I go check it out?

    Thanks for any help!

    If you take a few more pics of the side of the engine, I could tell you a little more about it. If you really want an accurate identification, check with the guys over at russianiron.com and they can tell you what is original on it, etc...
    It looks to be in good shape. The flatheads are good engines, but you will find them a little underpowered even by RPOC standards, but they can be made reliable. If I were purchasing it, I would be ready to pay 4k or so, depending on the quality of the work, and how well it runs.I have seen them go for more or less than this, but much higher and it would have to be an excellent example.
    I personally would keep the engine that is in it, but If you are wanting a daily commuter, a bmw engine swap is possible. You will want to go to russianiron.com and talk to a guy called Bural about the swap. The russian gearbox should be used with the bmw engine to keep reverse, and to make sure the drive shaft rotates the correct way to go forward. (BMW trans has a backwards rotation for a russian final drive) The transmission case has to be modified to do the swap, but the engine mounts right in with the original frame mounts

    Need better pictures. Does it have the original 2WD differential with locker?
    If it is really am MV750 (with star stamped military parts) with original locker and proper accessories the $$ is about right.

    I have one and the engine are rather strong but you are going to cruise at 40-45mph, nothing more.
    This is not the bike to purchase and swap motors. This is a rare bike.

    Here are two more pics he sent me. I'll see if he can take more and send them.

    Unfortunately the pics are not that good.

    matman1972, what modification is required? Something you can't put back to original condition? If I get it I'm not really planning on swapping engines out...at least not for the foreseeable future. Just more or less interested in whether or not it can be done.



    RomaDakota, were you just asking whether it had 2wd or had the original parts? It is 2wd but I don't know if it's the original locker.
    I kind of figured I would it's better to leave the engine that it has in it.

    I'm going to E-mail him to see about better pics and a few more details...


    Thanks for the replies so far. Keep them coming!

    Material has to be added to the transmission case so it will bolt up the the bmw engine. It is not undoable. If you can check the engine, final drive etc for the star stampings because it would be a shame to chop up a real mb750

    Well that settles that. I don't want to chop the bike up. Where would these Star stampings be located? Got pics?
    The bike is a little over an hour from me. I want to know what to look for/at when checking it out. I have another E-mail into the guy. Just waiting for a response.

    Thank you for your time and knowledge!

    Have him send you a top-down picture of the differential.

    Here is a pic of a non-locker 2wd diff (MT16)
    [​IMG]

    If it is a locker (MV750) it will have a shaft with an actuation arm at this location.

    Also the frame will have places on it for the actuation of the locker system if it is a true MV750 (near the horn). I think I can see the placard on the toolbox tank explaining the use of the locker.

    Here are examples of star stamps -

    The stamps should be visible on the heads, tranny final drive and wheel hubs. They are even on the inside ;-)

    I think this would be a very bad purchase for you. I believe you need to give me this address and phone number so I can go speak with this seller about tempting you with such an awful bike. I will confiscate it (even if it requires a cash transaction to do so) and quarantine it in my garage.:deal






    Good luck with the purchase.

    He did say it was the locking differential. Were there more than one type? I let him know I was interested in pictures of the locker. He hasn't got back with me yet.


    Thanks for sharing your knowledge, the pics, and the information!

    I hate when folks temp me with bad purchases. Thanks for looking out for me...Hey, wait a minute! :lol3
    I have been looking for something..."different" to tinker with. Can't get too much different than a Dnepr!

    So, besides the obvious on any bike, what kind of things need attention, extra attention on a regular basis on these bikes?

    Ummmmmm... everything? :lol3

    Like the old Packard ads used to say, "Ask the man who owns one...."

    And yes, I own one.


    One minute you will say "this thing is built like a tank!"
    The next minute you will say "what the #$@$ did they build it like this for?"

    It all depends on who 'rebuilt' the thing most recently. If done to American standards, I'd say it would be ok, but like an old tractor / car / etc. If it was rebuilt to Russian standards, be prepared for anything.

    But, you will not find anything as unique for the price. However, $6500 is a bit steep, unless its perfect, mechanically and looks wise.

    Hmmmm, what am I getting myself into. :evil

    More pics!

    I believe this is the lever that was mentioned...

    the undercarriage...

    From the owner...

    1. Engine and tranny are stock. The only additions/ non-stock items are a light I added to the side car and the axe is not original.
    2. I did the work, and have recipts for what I purchased.
    3. I went through the transmission and final drives just to make sure no obvious issues.
    4. I have owned it since 02 and finally got time to refurbish it this past year. I am selling it to make room for another project.

    It won't win many "best of show" awards but it looks to be a solid unit in good shape.
    EDIT: Am I correct in assuming this is a 6v system? Do I need to learn to speak Russian now?

    Well it looks good from pictures. He is mistaken about awards ;-)
    I'd say the big parts are there and now worth a looksie.
    Locker-diff looks good. Yes, it is 6V.

    Mine has a bit more patina :wink:

    Looks like a rattle can paint job, Nothing wrong with that, It's what I have on my 650 ural, and I am very happy with it.
    [​IMG]
    There is a lot available in english for it, and several parts sites that will have stuff available. You won't need to brush up on your russian. I am planning on getting a second rig sometime after we get our next house purchased, but rather than going the new 750 route, I also will be looking at flathead 2wd units.
    The one you are looking at is nice, and if it is a military version and not just a painted K bike, it is one I would definitely have a look at, but check it out well, and see if he will back off the 6500 a little. That is about what I have seen ones go for that had more professional paint jobs, etc go for.
    I believe it is a 6 volt system, but someone with more experience can probably chime in.

    Indeed, a pricy conversation piece. Allow plenty of extra time to commute back and forth to those back woods logging roads, you might want to play on -- not like these get much over 45 mph.

    Well, it's half the price of a new Patrol and about a hundred times more unique.


    But I wouldn't know a cool bike if it passed me in a sandwash! :lol3

    The "not win any awards" was something I said and to be honest it may win some. It's pretty clean.

    It has been painted so that should count in the price department I would think. Original patina would be much better.
    I was just talking with a good semi-local BMW tech. He has a "99" Chang(?). From the conversation I had with him I don't know if I really want to mess with this at this point in time.
    Bottom line...It looks like a good bike, maybe a little over priced but he did say obo/trade. If I'm going to be spending money now on a bike It's going to have to go at least 55mph. I'd get run over riding that around here.

    I WILL check out the build thread RomaDakota. Thanks!

    If anyone wants the contact info of the seller PM me.

    Yep! It would take longer to get there than the day is long! :D

    Definitely a unique rig!

    Thanks for the Dnepr 101 lessons folks!
