I rode my '06 yz450 today for the first time and I Love this bike. Before I bought this I had an '02 Honda CR250. I was still skeptical about 4 strokes over 2 strokes but now I am not. Especially for an older guy like me. When you need power it is there. I have always been a Honda guy and to an extent I still am but this bike is great. I installed taller bars, moved the forks up and set the sag tp 98 mm.
