Torque and power are two important concepts in motorcycle performance.
Torque is a measure of the rotational force produced by an engine. It is expressed in Newton-meters (Nm) or foot-pounds (ft-lb). Torque is what allows a motorcycle to accelerate, climb hills, and carry heavy loads.
Power is a measure of the rate at which work is done. It is expressed in horsepower (hp) or kilowatts (kW). Power is what determines a motorcycle's top speed.
