i currently ride a 2005 crf250 and a 2000 cr250. i plan on buying a newer cr250. probably in the 05-07 range. i hear so much about how much less power the newer cr250s have. will i really be disappointed with a newer cr250? i am a fairly agressive rider and i usually ride on supercross/motocross style tracks. i really like the two stroke over the four stroke 250.
