I'll put it like this... I may be a Suzuki guy, and I love my DRZ400 dearly. But if I would sell. I would opt for a 01 or 02 426. even though its 2010 next year. If that doesnt convince you... then I dont know what will.
EDIT: people keep saying there heavy... honestly, where do you guy's come up with this stuff? My 400E has a 285lb curb weight and I dont really have a problem with it, but I am 5'11 198lb's and I work out everyday, so that may be why.
i just traded my 2005 drz250 for a 2002 yz426f and man did i get GREAT deal!!! i'm very pleased. especially since i've been struggling to race harescrambles on the drz for the past season... oh and it weighed 251lbs dry!!! now comparing that to the 231lb weight of this 426 this bike feels like a feather weight!!! hell even my buddy's ktm 450xcw weighs 450+ lbs. yeah it's mostly because of the e-starts on both the bikes but this 426 makes sick power. i've ridden his xcw and think i'll have very little problem keeping up with him now. oh, i'm also 5'11" 194ish pounds and work out 3 times a week to stay in race shape(not to mention turning laps on my 9 mile hare scramble practice loop that's out my back door ) i get to race this yz this sunday and see what kind of fine tuning i need to do to get it set up. i'm also anxious to see how i place now on this thing. i'm currently about at the bottom of c class it's my first season
