cc usually refers to the unit of motorcycle displacement. For example, a 125 motorcycle is a vehicle with a displacement of 125CC. The following is a detailed introduction to displacement: Size: The smaller the displacement, the more fuel-efficient it is; the larger the displacement, the greater the power and the less fuel-efficient it is. Displacement per unit is usually used as the basis for evaluating the size of different engines. It is the sum of the working volumes of all cylinders in the engine, which is the volume swept by the piston from top dead center to bottom dead center multiplied by the number of cylinders. Function: Displacement is a relatively important structural parameter that can comprehensively measure the size of the engine. The performance indicators of the engine are closely related to the displacement.
