Why do motorcycles rev higher than cars?

Motorcycles typically rev higher than cars because of the fundamental differences in their design and purpose.

Firstly, motorcycles are generally designed to be smaller and lighter than cars, which means that their engines must be smaller too. To compensate for the smaller engine size, motorcycle engines have a higher power-to-weight ratio than car engines. This means that the engine must work harder to produce the same amount of power, resulting in a higher rev range.

Secondly, motorcycles have a different transmission system than cars. Most motorcycles use a manual transmission, which means that the rider must shift gears to keep the engine in the optimal rev range. This allows for more precise control over the engine's output and allows the rider to keep the engine running at higher RPMs for longer periods of time.

Finally, motorcycles are designed for speed and agility, which means that they need to be able to accelerate quickly and reach high speeds. This requires a higher rev range, as the engine needs to be able to produce more power quickly.

In conclusion, motorcycles rev higher than cars because they are designed for speed and agility, have a higher power-to-weight ratio, and use a manual transmission system that allows for more precise control over the engine's output.
