I'm 5'11 and 210lbs. I'm really into 2 strokes. I would only want a 2 stroke. I need a bike that would last me 3-5 years. I'm looking for something under $2200. I currently have a ltr-450 and I want a dirt bike. I need something fast enough to keep up with my older brothers crf 450. I'm not gonna race. I will be ridin on the streets and in the woods. It doesn't matter which manufacturer makes it. If there isn't much of a difference between a 125 or a 250 It wouldn't matter which is recommended. Please help. Thank you
