Well, I haven't ridden any 06-07 YZF yet. So I kinda need your guys help. I am going to get a new bike soon, possibly. But my major deciding decision is the following questions: 1.How light(in the corners, in the air, and overall) does the 06-07 YZ450F feel compared to a 06-07 YZ250F? 2.How does a 06-07 YZ450F turn/corner compared to a 06-07 YZ250F? 3.How is the power of a 06-07 YZ450F compared to a 06-07 YZ250F?
