I agree with you on some of that snook, im not 100% against 4 strokes. As a 17 year old kid though, i cant afford to buy a brand new 250f, and cant afford the consequences of buying a used ticking time bomb. I think you pretty much answered me 125 or 250 question right there. I wouldnt even consider myself a midpack C rider yet, so I think its obvious I shouldnt be on a 250 yet. Theres a nice 2006 cr125 that a gy wants to sell me for 1800, but I have heard they dont have near as good of engines and the yz125s do, so im not sure which I will get.
