Ah ok thanks, so do you think 4,970 miles is a lot for a 2010 model, the top end being rebuilt at 3,728 miles. He said it isn't very high and it's roughly 1,242 miles a year. I thought it was a bit high, what kind of mileage do people get out of the top and bottom end? I don't want to trade if it's not worth it because my 09 yz250 is a very low hour bike
