...bought my '04 plate 12GS in March, just under 23k on the clock, one owner, seemed in great condition apart from some corrosion on the engine plate. Have put 5k on it myself since then, and it's been fab. Only issues to date are I had to replace the rear brake disc 2 weeks ago which had warped slightly having worn thin (previous owner I think must have trailed his foot on the brake a lot!) - can't be sure, but I think was probably on its way out when I bought it as it was always running a bit hot. With the new disc, though it still runs warmer than the front, which I'd expect, it's nowhere near as hot as the previous disc. Guess that's what you call experience now. Only other prob to date is, sod's law being what it is, now the weather's turned colder, my right heated grip died on me on Monday last week. But apart from that, I love my GS which has been totally trouble free - and I ride it most days as I use it for commuting as well as for fun. So they're not all bad...
