No, not all motorcycles have a rev limiter, but many modern motorcycles do come equipped with one. A rev limiter is a safety feature built into the engine management system that limits the maximum engine speed (RPM) to prevent excessive revving and potential damage to the engine.
The presence of a rev limiter varies depending on the make, model, and year of the motorcycle. Some older or more basic motorcycles may not have a rev limiter, especially if they are designed for off-road or racing purposes where the rider may need full control over the engine's RPM.
It helps ensure that the engine operates within a safe range of RPMs and can also aid in compliance with noise and emissions regulations.
It's important to note that the specific details of rev limiters, including the RPM limit and the way they are implemented, can vary between different motorcycles and manufacturers.
