I am looking at making the jump from my trusty KDX 200 (not stock) to a WR 450 because I want mo' powa! I'm 6'3 and 195lbs, so I don't know if the WR 250 would be beafy enough to justify switching. I ride mostly Western single track trails in the hills / mountains and am concerned about the additional weight being more than I bargained for. I am an experienced rider, so I've no doubt I can handle the bigger bike, but I'm wondering if anyone else out there has made this upgrade (or similar jump), and if they wish they hadn't, or if the weight gain is made up for in power. Also, how does the stock suspension handle compared to the KDX? And last--does the '05 actually handle better than the '04?
