Ok, HP = torque in ft/lbs x rpm. Power-to-weight is the total wgt of the bike divided by HP. So a 2008 Dukati 1098 V2 is 377 lbs dry and 180 HP and a 2008 R6 is 366 lbs dry and 110 HP. By my calculations the Dukati and Yamaha R6 have power-to-weight calculations of 2 and 3 hp per lb respectively, so how do you interpret that? I know the rider's weight is a major factor and this was not factored in.
