Intuitively speaking, with 2500 tailguards, the exhaust pipe of motorcycle is loud, which will be considered as more powerful, but in fact it is not completely so. The power of a car is much larger than that of a motorcycle, but it is basically silent or small. Motorcycles are louder than cars, mainly looking at two points: the number of cylinders and the design of exhaust pipes.

At present, motorcycles have single cylinder, double cylinder and four cylinder. The greater the emissions, the more cylinders there are. Relatively speaking, the sound of a single cylinder is yes, because when the piston reciprocates, the power output from the engine to the motorcycle has obvious differences at different time points of the whole cycle. However, if the number of cylinders is large or even, because the running state of each cylinder is different, the power output will be balanced, which will make the automobile run more stably, and the vibration caused by exhaust will not make a great noise.
