well I got 6k out of my original bt 20's, don't think I ride too hard, lol would like to get more miles out of my tires, its warm 9 months a year,so I ride alot.
my friend paid 5000 for an 05 in good condition, I paid 5500 for an 07 with 140 miles and a warranty, you have to look for deals, e-bay!:rockon::rockon:
