What is the sound of a motorcycle passing by?
2 Answers
The sound of a motorcycle passing by is the noise emitted by the engine, as it lacks a muffler. Disc brake noise: When a motorcycle goes over bumps or experiences vibrations, the brake pads hitting the metal produce a clanging sound, which is definitely an issue with the disc brake. Rear brake noise: Such sounds are often caused by water or dust inside the brake drum, which does not affect braking performance. However, please note that excessive wear of the asbestos layer on the brake pads can also lead to this phenomenon. If this persists for a long time, it is recommended to replace the brake pads. Engine noise: The causes of this issue are relatively complex, and it is advisable to visit a specialized repair shop for inspection and maintenance. Knocking sound caused by detonation: When the engine suddenly accelerates or the motorcycle is climbing a slope, a continuous sharp "tapping" sound from inside the cylinder indicates knocking caused by detonation. Common causes include an overheated engine, excessive carbon buildup in the combustion chamber, low heat range spark plugs, use of low-octane gasoline, or advanced ignition timing.
As a seasoned motorcyclist, the sound of a bike passing by is like the soundtrack of my life. At startup, the engine's deep rumble resembles a lion awakening; when accelerating, the exhaust roar escalates into a high-pitched howl—especially on sport bikes, where the sharp, piercing tone blends with the hiss of tires gripping the pavement and the rush of wind, creating a dynamic symphony. The sound ebbs and flows with speed: a gentle hum during city cruising transforms into a thunderous roar at highway speeds, accompanied by the rhythmic clatter of chains and drivetrain components. Different engine types offer distinct acoustics—the rich, bass-heavy growl of a V-twin is intoxicating, while the high-frequency scream of an inline-four feels more aggressive. Many riders modify their exhausts to amplify the sound, chasing that visceral thrill, though it requires balancing safety and regulations. Ultimately, that sound embodies the essence of freedom and adventure.
