now im no engineer but all the adventures have wire wheels that are all out of true and not only run out side to side but oscilate quite bad as well and my mate brand new one does this straight outta cannons . coupled with the free play allowed by bmw on the rear drive bearing id say that paralever /swingarm whatever you wanna call it has to take a bloody lot of un natural constant side forces / vibes . if there was a small flaw or a stone hit it etc then surly this would help in the thing blowing its self to bits . i read somewhere that the main stand bangs against it as you ride along . gonna check mine later . just a thought
Mmmmm, you put forward some valid points

Dear BMW,
