With trail-optimized dimensions, the new YFZ450X inherits all the high performance features of its brother the YFZ450R but puts it all together in a woods friendly package. Now you can blast around trees, stumps, logs and almost anything else that gets in your way. And with five consecutive GNCC titles in its bloodline, the only question is, why would you race anything else?
