Been riding an 07 CRF150F for the last 4 years, along with a few rides on my dad's 09 420 fourtrax. Looking to buy a 400 or 450. On the classifieds near me I can only find KFX's and DVX's, been looking around for a 400ex like mad but can't find one anywhere worth looking at. Any opinions on, say, an 06 DVX 400? Found one that looked mint for a good price. Also, for those who want to know, I'm 5'9" at 140 pounds without gear. I have used a few YFZ 450's and a KFX 400 once (not enough to really get a feel for the KFX) so I do have a bit of experience with these bikes and I'm not afraid of the power or anything. If anyone has any suggestions, shoot!
