Hey guys. Just a bit stumped between the two. Have had an 04 and 05 CRF 450, and a few 02 KX 250 two strokes. Just wondering what I should take? 08 CRF 450 with about 13 hours, SSS suspension, full hindle exhaust, pretty mint bike or an 09 KX450F with 70 hours, been raced hard but maintained, new plastics, suspension has been done, Yosh pipe. Brand new piston, rings, and cam chain. Experienced rider, lots of track riding with friends and alot of pit riding. Any problems common to either of the two? Thanks alot.
