Ok. This will sound funny to everyone here. Well, I rode a buddy's green sticker 2005 wr 250 last week and I thought it was great: good easy to use power; good suspension; easy to ride; light but not too light to stay on the ground.... My current rides are 2002 kx 125 and a 2003 klx 300......I weigh 165 lbs and am a novice rider. Well guess what, that 2005 wr 250 is actually a 2005 wr 450!!! My buddy had a spare 250 rr fender on to save his original 450 one from damage. How funny huh?? He also has a wr 426 hat he is selling, but how much more does the 426 bike weigh than the 2005 wr 450?
