I just passed 10,000 miles on my '06 TW, which was bought with 1 mile on the odometer. It's leaking oil as the 06's are prone to do (especially mine, 2 warranty base gasket replacements already, one home job coming), but it still runs like it did the day I bought it.
Congrats........ I just passed 9,000 miles on my 06.... I have a verrrrrrrrrrrrrrrrrrrrrry slow oil leak.. My wife's 06 has 6,000+ miles now.. She has an even smaller oil leak. Great fun with these bikes.. OMM.
