What I can remember after decades of working with BMW motorcycles
Special work tools for BMW motorcycles, R50/5 to R75/5, R60/6 to R90S, R60/7 to R100RS. Capital Cycle Corporation
Spezialwerkzeuge fur BMW Motorrader
BMW used Matra tools. About 1/3 were not needed, another 1/3 were of very poor design and the rest were either total junk or very good. Ed Korn made far better tools. Ray Bunch made the best that I have ever seen.
