Seems that most of the replies here relate to 1150 GS' but I was shocked to note earlier that the silver paint on my 03 DAKAR was starting to peel off at the top of BOTH forks, right next to the fork seals - the brace itself looks fine. I first noticed it on the sponge I was using to clean it, so it was not being handled roughly. The bike is not quite a year old yet and it is after all a BMW, so I admit to being a touch disappointed.
I do very little Winter riding as I know the salt can play havoc with the paintwork, but if I ever take it out on salty roads, I will nearly always wash it down, will always dry it off and let the engine idle for a good while before putting it back in the shed.
In fairness I have not mentioned this to the dealer yet, but when I rang him to check whether a faulty "low petrol" indicator would be repaired under warranty after its 1st birthday, he told me that it was. I wonder whether the guarantee will also cover the flaking paint. Being paranoid, I have now checked the rest of the bike and that seems fine.
