Does anybody know what the stock horsepower is on an XR600R? I read that it gets its peak power around 6500 rpm. And that it produces 35 lbs/ft of torque. The formula for Horse Power is..... hp=rpm x torque divided by 5252 So if you do... 6500 x 35 divided by 5252 That = hp=43 That seems like a logical calculation. Correct me if I'm wrong.
