Thanks guys. its a new world for me as I only ever had 1 problem with the 75/5 and that was the drive shaft, it spun in the taper.
Aha! A man after my own heart. I hate that tapered joint with a cold burning hatred as I have had two come loose on me over the years. Others laugh at me because THEY have never had a problem.
IMLHO it was a case of BMW saying "we can do this, so lets". Why oh why couldn't they have used a splined joint like everyone else?
And whilst we are on the topic, would a gearbox input shaft spigot bearing have killed them? or perhaps two opposed universal joints in the drive shaft instead of the rinky-dink way they went about it.
Growl snarl etc....I reckon I'm entitled to be grumpy on the above topics, been riding the rotten things since 1978 [but I really do love them for other reasons].
And I haven't even mentioned ATE single sided calipers - BMW were the first manufacturer to fit twin disc front brakes because a single ATE single sided is less effective than the lovely drum it replaced.
