Only got 8k on the back. Could have gotten more but I neglected the tire pressure. Probably too low cause my tread cupped and was hummin real bad when in a twisty. Changed the front at 9k cause it was at the wear bars. I ride 2up a lot but wife only weighs 115lbs. I have to admit though I am pretty heavy on the throttle. Out of 1rst gear by 3k. 4k and up the whole way to 5th.
