I keep waffling on what my new bike is gonna be, YZ 250F or 450F. I am 210 lbs. race expert off-road and play ride moto occasionally. I live in NW Washington and the majority of my riding is tight ,rocky,rooty,hilly,muddy trailriding w/ the occasional jaunt to the desert on the other side of the mountains. I am just worried I'll be stalling the 450 alot or that my results will suffer due to added fatigue from a heavier more powerful bike than what I ride now, a Yz 250. I guess I am looking for people who've made the switch from 250 to 450f and ride and race in similar conditions and see if they wish they had gotten a 250f instead.
