I have a 99' 400F and I am debating wheather to keep the beast or at the end of this season sell it and look for a very nice 426. My 400 has very low hours and has been pampered its whole life. Now I'm wondering if going to a 20002 426 will be a significant improvement before I have to do some major work on my bike. I've ridden a 2000 426 and it feels like a very different bike. The power is very harsh at the low end but it feels more nimble than my bike. I would get a brand new 450 but I want 5sp for open desert. And I don't need electric start, headlight, taillight, kickstand etc so that rules out the WR. I've ridden an 04 CRF 450 and I felt cramped and it was so small I felt like I was going to brake it(I'm 6' 4"). I don't feel like spending > 8000 on a Kentucky Trash Masher. And I won't ride a Kawazuki or Suzisaki. I may just have to go exotic. Sorry, I'm picky. I may just keep the beast. I am very comfortable with it. Any advise?
