Those of us who forget history are doomed to repeat it...
My '83 R100 suffered from exhaust valve recession (metallurgical problems), premature clutch failure, diode board melt-down, etc...
My wife's 83 R80 ST diode board & alternator rotor
my R100 GS alternator rotor... premature rear shock failure, premature gearbox trans output shaft bearing failure (twice) pulled cylinder stud (twice) due [presumably] to voids in block casting - environmental concerns had caused casting process to change slightly and they had not yet got it right maybe?
My R11GS... well, actually, not too bad until hit by a cretin in a pickup truck (with me on-board, naturally)
My first R11S - pretty good till totalled
My second R11S - servo brakes no prob, but some ABS brake gremlin in the wiring harness... fixed(ish) just after warranty by replacing lots of things that weren't the problem first. (but covered under good will)
My 06 GS - near final drive at 24k just before 3 yr warranty ran out...
headlight cluster just after warranty ran out (but covered under "Great dealer who could wrestle the zone rep to the ground"
Fact is, all that tractor-like reliability was more in evidence when these machines had tractor-like power-to-weight ratios and tractor-like levels of complexity.
With all my friends with Ducs and their $700 valve adjustment service calls and two month parts-on-order waiting periods, I think I'll stick with these faulty once-bavarian machines, myself... better the devil I know (and I have boxes of bits and bobs of spares for them)
The final drive failures are vexing... my dealer's theories make sense to me (they are oldest surviving dealership in the US... been at it since before I was born which was in '58)
they figure that BMW forgot how to assemble things with the right tolerance and feel.... slight mis-alignments of bearings is causing failures that have to do with mis-stressing bearings that are certainly rated for the load they are under if aligned correctly.... this being more a process design issue than a mechanical design issue, but leaving you just as screwed when it all goes horribly wrong...
oddly enough, rear end failure on mine turned out to be the pinion gear bearing (blind hole end) not the bearings that support the wheel itself...
no one copped to having seen one of those fail early before
truth be known, the best way to improve reliability of most of these machines is to drive them in such a way that they are no longer fun...
the more under-stressed they are, the longer they will last....
but who wants to do that?
As far as the transit is concerned.... comparing humming birds to elephants...
with regard to fit and finish as well as lots of other aspects...
If you could get your transit to wheelie off the line and corner like a bike....well... you know.
I have a wheelbarrow that is at least forty years old and has had the wheel bearings lubricated once (last year) and it works almost as well as new!
as far as getting away with it... BMW sells things... that's what they do - the fact that some of us actually ride crap out of them is secondary....
most of their tremendously fast-maneuverable cars are sold to people who sit in traffic with them for three miles a day and then park... many of the bikes they sell come out of the garage once a week and get very few miles on them.... we are a rather different demographic but statistically all those bikes sitting in garages doing nothing are improving the reliability numbers
