Vintage BMW Motorcycle Owners

I can send or post a scan of my original R51-71 English handbook if you need it.

The listing has been pulled, but I think it was offered in the USA a year or so ago, as the Italian origin rings a bell. A friend was looking into it. IF it is the same one, it is a nice looking bike, but the crankcase halves didn't match, it was unlikely that the engine and frame numbers were of th...

It probably was the best example........they are all horrible. Even the basic geometry is wrong on all the repops.

Here is the page from the parts book, although it really does not show the rack clearly. The photos from a later parts book show it better.

It looks real based on the picture in my parts book, especially with the curved fender mount on the front of it.

Mine is not, so I can't provide dimensions.

I pulled a string line from the rear edge of rear tire to the front edge of the front tire. The string just touches the other tire edges, so the front and rear wheels are in a straight line. It has always tracked and driven well so I am pretty confident that is right. The offset I measured was the d...

I did look at my bike and I now think I understand your issue. Using a long metal straightedge, the right side of my frame has roughly 35mm of offset from where the engine mounts to where the rear drive mounts. That is about as close as I can measure without taking things apart. I don't have a long ...

I may not understand your problem correctly, but it sounds like it might be an engine spacer issue. There are spacers on both sides of the engine that are unequal. I'll take a look at mine later today. Did your alignment shop have the rear drive when they did the work? I think it would be necessary ...

While I think it it is possible to build a complete R75 from repop parts, the horror stories I have heard about R75 transmissions kept me from ever thinking about owning one. Anecdotally, I have heard that: 1. There was a factory design flaw in the transmission that must be corrected to prevent fail...

I might add that there are some interesting vintage car and motorcycle fairs. The best known are Veterama in April and October in Mannheim. There is also a series of similar Technorama fairs in Kassel, Ulm and Hildesheim in March, May and September if your timing works.
