oh yes!, I have corrosion on my crash bars also, just like many GSAs. The dealer said that it was not worth changing them yet because the replacements would do the same!. He said its worth waiting a bit until "they got the quallity right". Im thinking that if I dont make some kind of official complaint soon, BMW way ask why I didnt earlier, and say sorry you left it too long. the bike is a march 06 GSA.
I cant get off the thing, love it!
I have to say, I had a brand new Harley some years ago, the clutch cable wore through the paint on the headstock, the ally went all white and frosty and the crome rims rusted within months, I also had a triumph R3, you could not ride that thing anywhere near rain, the finnish was, how can I say, very dissapointing!
