Hey guys hows it going. I started riding when I was 12 I am now 18. I rode a 400ex until I was 14, then got a YZ125. I had a desert rat family, we went to the desert almost every weekend during the season. I rode the 125 for 2 and a half years, at the desert, hardpack/gordons. Then I started going to the track a lot for fun, I was just about to move up to a 250 until my family moved we sold everything due to no place to store motorhome, trailer, bikes, etc. Now I have saved up enough money to buy another bike. Question is I weigh 150lb's and I haven't ridden a big bike for a year and a half, Should I buy a 450 since I will probably grow into it, or just stick with a 250f. The bike will be used 80% desert 20% track. 450-Too much power? Not needed? 250-Not enough? end up selling in a year for a 450? Just thought you guys could help me make my decision.
