What do you blokes do with your bikes - store them in salt water?
I've done 9k miles on my RTLC in about 18 months and it's still immaculate, as far as I can see.
Maybe I need better glasses...
You maybe do need better glasses. Strip away some plastic, give it a good detailed clean and you will find it if it's been anywhere near a winter road. Mine is ridden, rattled up to 9.5K in around 9 months or so, cleaned every weekend, ACF50'd for winter, a Pet dryer to dry it off and a squirt of FS365 afterwards. Outwardly it looks showroom, dig under the surface and you can see it going.
Mine looks brand new compared to dudgeman's based on his pictures above, but it's starting, and once it starts it won't stop. I have to say Dudgemans is the worst I've seen, but I also have to say I was in a similar position, 1 year old Tiger 1050, same sort of corrosion as Dudgeman's RT, and I went through everything to get it done, tried rejecting it, got a solicitor involved and finally got to the point where they offered to rebuild the engine with new cases, but still insisting it was normal wear and tear. At the very least BMW have stumped up and said "OK, will sort it out" with a minimum of stress.
Like I said in an earlier post, no amount of ACF50 or FS365 etc is going to prevent poorly prepared surfaces from going. I don't think it's even the shit water based paint, I think BMW have a manufacturing problem and need to sort it.
My dealer has a Black Engined GSA in next week with my RT, full engine swap due to paint defects, it's only a few months old. (PS They don't like the word corrosion in warranty claims, paint defect is the buzz phrase)
