First of all you have to assume that the motorcycle has a derating power kit installed and accept that now the motorcycle is riding at slower speeds. The kit reduces the power in high revolutions sacrificing less power in low and mid revolutions. It forces drivers to change gear up and down earlier and more frequently losing acceleration capacity and top speed. Driving efficiently, you can reduce your fuel consumption.
