i found an 09 yz450 for 3100 locally for sale. i was looking for a 250f in that price range but this bike looks pretty nice and i might have to go look at it to check it out. if the bike is in good condition, is 3100 too low of a price? i have yet to take to the seller, but i'm thinking that the bike was raced. for those who have 450's and take good care of them, how long do you ride on a top end? i will post the link to the add later.
