Is 400cc Considered a Large Displacement?

[McAiden]

400cc displacement is equivalent to 0.4L. A larger displacement means the engine releases more energy per unit time (converting chemical energy from fuel into mechanical energy), resulting in better "power performance." This can be likened to comparing a teenage boy to a healthy adult—the adult naturally performs physical tasks more efficiently. Below is additional information: Displacement calculation method: Cylinder cross-sectional area × stroke × number of cylinders = total displacement in cc. Stroke—42.5mm = 4.25cm. Bore—67.0mm = 6.7cm. Cross-sectional area—3.35 × 3.35 × 3.1416 = 35.25. Cross-sectional area 35.25 × stroke 4.25 × number of cylinders 4 = total displacement 599cc.
