I weight 180lb without gear, 6-2". I switched from an 02 CRF450R to an 05 200EXC, Yes the power is not there compared to the 450, but for woods I definetly did not need the power of the 450. I do not feel like I can ride any faster on the 200, but I can last longer and I feel stable and more confident. I have really enjoyed my switch and I am very happy about it. Of course I still have the 450, if I feel so inclined to beat myself of some single track. As said before get more seat time. The only down side I found with the 200 is I did miss the big hit of the 450, I just needed to figure out how to ride the 200 and I did not care about it. The 450 definetly made me a lazier rider, since I new I had enough power to help me out. Ride the 200 for a few days if you can and see how you like it, also as stated try a 250 if you like having more power.
