well I've decided on a 450f. My local shop has 2 clean low hour 450's.A 2005 crf 450 and a 2007 yz450f. Both bikes are super clean and he knows the history of both bikes and the owners. I have mostly ridden Honda and have rode an 05 crf already and it was ok,felt a little heavy. I never rode a yz 450 and his shop insurance doesn't allow test rides. He's a really cool guy and backs up every bike he sells. If there is/was a problem with the bike after the sale,he would take care of it. I heard alot about hondas but not much about yammies. Any help would be great. Also there would be some tight,woods trails ridden and i hear 450's dont like that,get hot. Any one of them a little better in these conditions?
