Welp, I figured you guys would have those responses
The good news, is hp wise, I'm pretty sure it was dead even. So anyone know the hp for a 2011 KX250F? Second, yes it was on pavement. The thing is, here is why my opinion stands. Like Burn said If we wanna compare, the 250F has smoother broader power. So although these two seem to be equal, you gotta compare the whole track. So the question was asked, if the same rider was on both bikes, who would win. If the rider never ever made a mistake, the 250F would out perform the 144, just on the mere fact that it has an easier time doing certain corners and jumps. Then, add in the fact that no one, ever does a complete moto, without atleast a small mistake. I feel the 2 stroke cc vs 4 stroke cc is a fair fight. Again, it's my opinion, but I just think the 250 vs 250 is fair.
Something else to keep in mind here guys. My bike is about as maxed as I can go. Gorr porting and cylinder/head mods. Cases ported and matched. So my point is, the 250F as stock has a lot of potential still too, as we know Pro Circuit gets about 10 more hp.
