I will be purchasing a new bike at the end of September. It will be blue! The question I have is.... WR 450 or WR250? I live in the Northeast and 70% of my riding is on tight rocky single track. Will the 450 be to much? I love hill climbs and the occasional natural jump. (read hard landing) Will the 450 bottom easily? Does the 250 have enough power? My current XR 250 has served me well, but after riding street bikes for so many years I am disgusted with how little power it makes. And since I am getting older, not younger, the suspension is killing me. What are your opinions? I love to trail ride, but I also love to open it up occasionally.... but not at the sacrifice of low end grunt. I am really split on this so any opinions will be greatly appreciated.
