If you are used to riding a kxf250 then I would be careful of your confidence towards a yzf450! difference is night and day! Especially 4 gear race spec on the yam, As an avid rider of the yam 450 titanium 5 valve any 250 four stroke is child’s play in comparison no matter what you do to it, make a mm mistake with throttle game over! 250s for boys 450s for Men!

Good 1st post, I like where your head's at. Now wander over to Pro Motorcycle Racing section of the forum and start a thread about the YZ450F and why it dominates SX and outdoor.
