Hp = (Torque x rpm)/5250 The formula above would be correct if your Vmax had an electric motor measured at radius of 12 inches. This is not correct for a combustion engine. There are many factors which will determine the torque output of an engine. Such as a flywheel, the engines bore and stroke, piston weight, drive train, wheel diameter, etc. Look at the Dyno run for a Bone Stock bike from the web site. At approximately 6000 rpm, a maximum torque of 78.6 ft-lbs are recorded with 90 hp. This is far below the maximum horsepower reading at over 8000 rpm where it reads 106.6 hp and the torque at that point is below 70 ft-lbs. If the formula was correct, all engines would make the maximum torque when the maximum Hp is achieved but they don't. John .............................................
