Well I bought Jake's (adventure950) 03 KTM at 40 odd thousand miles, racked up another ten thousand miles before part exchanging it against a new 990s. Jakes wasnt wrong saying the clutch needed work in the forseeable future as the carrier failed on the way back from his house to mine the day i bought the bike!

That said in general terms the bike itself performed brilliantly and ran like a swiss watch, I've dragged it through river crossings, up mountains, done 1000 mile days 2 up, scratched with sportsbikes and offroaded with 250 strokers. at that sort of mileage you can anticipate some faults and these included. the clutch carrier bolt shearing off due to a worn indent on the back of the carrier (£120) the ignition barrel contacts corroding causing headlamps to not always work (cleaned up but replacement was £70 unless you wanted the key to match the fuel caps in which case £280)
A Battery failure (£130ish) A rear caliper that was completely U/S as a result of corrosion £160 and a fuel pump failure (Jake supplied me with a part used spare that did for me so dont know the cost) and to be fair the fuel pump failure had as much to do with my deep water play on salisbury plain as anything else

at the 55,000 mile service the valves were within spec and the cam chains were also within spec. replacing with the 990 was just because I could, not because I should neccesarily and I was sad not to put more miles on her
