What Causes Loud Motorcycle Noise?

[SanKaylee]

There are many factors that affect motorcycle noise, which can be summarized into the following categories: temperature, speed, load, and lubrication. Temperature: Some engine noises appear as the temperature rises, while others diminish with increasing temperature. The occurrence of certain noises is often accompanied by heating phenomena. Therefore, in addition to listening to the noise, it is also necessary to measure the temperature to aid in diagnosis. Speed: Noise has a certain relationship with engine speed and vehicle speed. Load: Load has a certain impact on noise. Generally, noise increases with the increase in load, which is a common pattern. Lubrication: Regardless of the type of noise, when lubrication conditions are poor, the noise is usually more severe.
