Looking for information on mounting a dnepr onto a BMW 1971 R75/5. Any information/advice would be much appreciated. Have had many bikes, including older BMW's but this will be my first sidecar owned and have never mounted one before. I have a welder I could use but have heard I could possible use some type of clamp instead as I'll be doing very light local riding. Anything anyone could tell me (like I'm a 1st grader since my existing knowledge is very minimal) would be much appreciated.
Thanks in advance
You can download the attachment manual on the Dnepr site I believe.
We make a mounting kit for the /5 BMW. It gives you two sub frames giving you all 4 mounting points. For the front lower mount you must cut off the non adjustable mount from the sidecar frame and weld on an adjustable one we supply. Every thing is 100% bolt on on the bike side of things.

Thanks...I will.
Thanks,
I'll check out your site.
You definitely need the subframe on the /5 frame. it is too weak for sidecar use.
Thanks, I'm looking at the side selling the sub-frames now. Are the rigs I've always seen, especially the /2's, without sub-frames just asking for trouble?
yup, the older Beemers, /2's, had heavier frames AND sidecar mounts. they were made to use sidecars if wanted. The /5, /6/7's were not made for sidecar use. the upper rear portion ofthe frames were especially too weak for mounting. lots of flex and bending from stress.you will need a "Z" shaped subframe, going under the engine to pass peg mounts, then up to just below the seat. and back a little if necessary there.Upper front is OK, if mounted high enough, close to the cross brace.
Thanks a ton for the info.
Accepting the fact that I'm looking a moron...
In your opinion, the expected results if mounting a dnepr sidecar to a '71 R75/5 would be...
Thanks again. It's very helpful.
That depends on you. It would be a good looking rig and probably suited to casual or city riding. High speed Interstate, loaded down riding might be a bit hard on it but I've seen a lot of rigs with smaller engines. If it fits the style of riding you will do, I'd say go for it.
The Dnepr sidecar is a tank on one wheel. Unlike a lot of the sidecars available in it's price range, it will easily adapt itself to another bike if you chose to go bigger in the future.
Where are you located? One of us may be near by.
Just be taking it on 2-lane back roads...probably never over 50mph...most possible weight for the whole rig at one time would be myself(180lbs), my wife(125lbs) on the back or in the car, and one of my kids (100lbs or 50lbs.
I'm located in Vermont.
Thanks for your info/help as I figure this out.
The expected results/effects of mounting the sidecar directly without the sub-frame?
(curiousity as I'm sure I'll get the sub-frame)
For safetys sake: Keep the wife in the car if all three of you are riding.
Keep the passenger (wife) in the car if two are riding.
Even with the heavy Dnepr car the chance of tipover is high with both of the heavier riders on the motorcycle.
Some 180#ers also carry ballast in the car when no passengers are riding.

The R75/5 frame will not support a sidecar safely without some sort of sub-framing. There's just not enough to work with. Whether it's called mounting brackets or whatever, some sort of intermediate design parts are neccessary to install the sidecar to the post /2 BMWs.
