i'm new to tt but i've browse quite a bit. i currently ride a 02 yz426f and i love it. i ride mostly mx and i love the power and the reliability. this was my first bike. i've had it for a couple of years now and i can throw it around pretty well know. i've ridden a buddies 04 yz450f and i was noticably faster on the first lap(in corners and jumping). i really liked it. i was also looking at the crf 450s too but i looked at the threads and it looked like everyone was having problems. looks like im going blue again. only if bubba would do the same. whats a good year yzf450 to look for?
