機車cc是什麼意思

"CC" in the context of motorcycles stands for "cubic centimeters." It is a unit of measurement used to indicate the displacement of the engine, which is the total volume of air and fuel that the engine can draw in during one complete cycle of all of the cylinders in the engine.

The engine displacement is calculated by multiplying the cylinder bore diameter by the stroke length and then multiplying that by the number of cylinders in the engine. The result is expressed in cubic centimeters (cc).

The displacement of a motorcycle engine is often used as a rough indicator of its performance, with larger displacement engines generally producing more power than smaller ones. However, other factors such as the design of the engine, the type of fuel used, and the tuning of the engine also play a significant role in a motorcycle's performance.
