i have an 09 fe570 i raced on the ice last winter.when spring came i rolled her into the trail,single track,pits and whellies down the road and to date was the nicest dirt bike i've ever owned.i just bought a 2010 fe390 and i must say it feels like a mountain bike with a motor in it.going up pit walls the bike gets better traction than the 570.the 390 just rules the single track hands down as well.i had a rmz450 and a couple of yz250f's and the ride was always twichy.too tight for rocks and roots.the fe suspension once used to will be your new best friend.a two year inspecton sticker doesn't hurt either :cheers:
