No, not all motorcycles have a clutch. While the majority of motorcycles do have a clutch system, there are some exceptions. In recent years, there has been an increase in the availability of motorcycles with automatic transmissions or semi-automatic transmissions, which eliminate the need for a traditional clutch.
Automatic motorcycles use a transmission system that automatically shifts gears based on engine speed and load conditions, similar to an automatic transmission in a car. These motorcycles typically do not require the rider to operate a clutch lever manually.
Semi-automatic motorcycles, also known as clutchless motorcycles, have a transmission system that allows the rider to shift gears without using a clutch lever. The shifting mechanism is typically operated by foot or hand controls, but the clutch engagement is done automatically.
