Hay guys! Well im looking for a bike. Iv been looking at the some of the 2010s. I was loking at all of em. But i maybe getting used. But i was mainly looking at the 10s and i was looking at the crf250r and the rmz250 because i like the new fuel injection feature. Or i may looking into a used 450. But i used to ride a ttr125 and i have ridden a yz250, yz250f, and a yz450f. I love them all! They are awesome bikes!~ But no affence to you two stroke lovers im sort of gona stick with a 4 stroke, but there is still the thought of getting a 2 stroke in my mind . But mainly four stroke. is there anything you would recomend? Any info on these bikes? Also what bout the later models of the yzf, crf, kxf, and the rmz? I hear hondas have valve problems but any info bout that. But im 15 years old 5'7 and like 170lbs but im gona be weighing like 145 at spring because ( wroking out) But what bike do you guys think would be right for me? thanks guys!
