These number seem so low... I'm not as familiar with the torques but only 37 for max hp on a 250f?

37 hp for a 250 4 stroke is high IMO, my 250 yz 2 stroke should be around 46

Those numbers are low. The 09 yz250 2 stroke made 41.3hp on motousa's dyno and the 09 crf250r made 34hp(highest 250f number that year on their dyno) on the same dyno. That's a pretty low number for a 250 2 stroke, usually they make around 46-50hp and these days the newest 250fs should be around or over 40hp. Motocrossaction got 46.85hp out of their stock yz250, 49.33hp with a PC works pipe and R-304 shorty and around 50hp out of a stock 250sx. Those numbers sound about right but, they also got 42.89hp out of a 250sxf on the same dyno.

Yeah Moto USA always seems to have much lower numbers than other sources.

Yeah after some research I seen most 250fs are 35 hp at minimum... its been a while since I looked at a 250f dyno.
