Why are motorcycles so loud?
I was just wondering, why are motorcycles so loud?
Motorcycles are typically louder than cars because of their engine design. Most motorcycles have single-piston engines, which require them to rev higher in order to achieve a similar level of power to larger car engines. This, in turn, causes the exhaust to make more noise as it expels combustion gases. Additionally, motorcycles are designed with a shorter exhaust system that doesn't muffle the sound as well as car exhausts.
