HMMMM...Hondas (450R) have been shown to be more reliable and better finished product (like always) but yet slower than the YFZ450. Now suzuki just introduced its 450 sport quad, that this is badazz. Even has underseat exhaust! Me, I have only ridden a motorcrossed out YFZ, and it was sweet. However I still miss my trick 88' Honda 250R. That was the ultimate machine, although mixing gas sucks.
