I currently have a 09 kx450f. I love the bike but looking to upgrade to a 13. Only complaint on the kawi is the turning. My bike before the kawi was a 09 yz450f liked that bike just wanted f.i. Now im stuck between the two. I havent got the chance to ride a 10+ yz yet and was wondering on how the rearward engine affected the balance of the bike? I sat on one last week and the seat seemed really hard? At this point im leaning towards the yz becuase of the price but if the kawi is overall alot better bike i would get the kx. Just looking for real world input? I've watched the shoot outs but they seem to be baised sometimes.
