Sure hope the electric start on your 50/5 worked a lot better than on my '71 60/5, which never saw a cold morning it would start on; but it was so much better than the Honda 350 that I didn't mind kick starting much. That already well used 60/5 made it all around North America in '76-77, including half way down Mexico, and back to the east coast, with a lot of very bad roads between (the Mexicans used to prepare back roads by dropping huge gravel in the road bed and letting the drivers crunch it). I fell in love with Beemers on that year+ long trip.
However, I appreciate what you're saying. I've never had frame problems, even with the sidecar on the '76 R90S, but am not so stupid to assume it means anything, necessarily, except possibly that I was lucky and/or much easier on my bikes than others. Who knows.

During the years 1974-1985 I was a member of the QLD BMW riders club. Legendary were the occurrences of broken sub-frames, and these mishaps were mainly on solos.
If someone wanted to build-up an outfit, they either used a complete pre-'69 model, or at least shoe-horned the /5, /6 motor into one.
(NB. My current, and first, outfit is my 4th BMW; from R25 to R100RS

From 1973 I owned a Moto Guzzi 850T
with the 'Telaio Rosso'-shape
frame. This is how to build a strong frame . . . . . not what BMW did with their twin-loop plus bolt on.
If I had the money, my R100RS engine would be mounted in a /2-type frame, or even a CJ.
I once rode it around the major holes on a road closed to ordinary traffic. The Ural tub & frame came through unscathed
, but . . . . . welds broke at the front of the downtubes, & the upper triple fork plate came close to breaking away on the centre hole.
● Some welding.
● A set of Perry's reduced trail T-clamps (which are beefier than stock).
● Addition of a cross-brace bridging upper rear-frame connection bolts, which makes battery access more difficult. I'm in the process of changing over to an external (to bike) automobile battery.
