I know this is an atv forum and everything but i know many of you own dirtibikes too. Well here is my question, should I buy a yzf426 or a crf450(crf a few hundred more than yzf), the only thing is I would have to have the crf shipped and I could pick up the yzf. I will be switching from a raptor to a dirtbike so how much of a difference is there between the two powerwize especially on an mx track?
