A Dynamometer can only measure actual power at the output location. Actual power produced AND delivered by an engine will be highest if measured at the crankshaft, lower at the transmission output shaft and even lower, still at the rear wheel. Rear wheel dynotest shows this bike get around 44-45 HP. This is not the true horsepower, to factor in what it would be truly at the crankshaft, and this is the rule of thumb, add a additional 25% to your rear wheel dynotest results and this bike has appox. 54-56 true horsepower.
