Noticed that the chrome header, on the underside especially, look like they are rusting. the surface is pitted and rough. I tried giving them a good clean today but it really didn't make it much better. I havent been looking that closely over the period i've had the bike but now coming to second service and towards the end of the warranty I was wondering if this sounded like something the dealer should fix? I have done about 18500 Km over a year and a half to give you some idea of the age. Anyone else noticed this? I saw a photo on a magazine website with a long term review that had similar rusty brown looking spots. This is not blue-ing of the chrome, more like pitting. Not too happy with the quality of the chrome as I though this should protect the pipes from rusting! Anyway, i'd be grateful to hear if anyone has any words of wisdom on this topic..
