No, motorcycles typically do not have thermostats in the same way that cars do. Motorcycles rely on simpler cooling systems compared to cars, and they generally do not have a thermostat to regulate the engine temperature.
In most motorcycles, air-cooling or liquid-cooling systems are used to dissipate heat from the engine. Air-cooled motorcycles rely on fins and airflow to cool the engine, while liquid-cooled motorcycles use a liquid coolant circulated through the engine and a radiator to cool the heated coolant.
Unlike cars, motorcycles usually lack a thermostat that automatically regulates the engine temperature by controlling the flow of coolant. Instead, the cooling systems in motorcycles are designed to maintain a balance between cooling and heating based on the airflow and the design of the cooling system itself.
