im soon going to buy a new yz450f. is there a world of difference between these 2 years? im 15, 135 lbs about 5'10" tall. im coming off of a 02 yz250f. im pretty sure that there are no 08's up here in this part of canada yet. im talking handling, i know the bike will have enough power to haul my 135 lbs ass around and it will have better handling then my 02 but is it worth the wait for the 08 to arrive. i will find a world of difference with the handling of an 07 anyways soo... help here please!
