No, air-cooled motorcycles do not have radiators. Instead of using a liquid cooling system like those found in water-cooled motorcycles, air-cooled motorcycles rely on air circulation to dissipate heat and keep the engine within a suitable operating temperature range.

In an air-cooled motorcycle, the engine is designed with cooling fins on the exterior surface of the cylinder and cylinder head. These fins increase the surface area and allow for better heat dissipation. As the motorcycle moves, air flows over the fins, carrying away the heat generated by the engine. The heat is then dispersed into the surrounding atmosphere.

By contrast, water-cooled motorcycles use a liquid coolant that circulates through the engine and a radiator. The coolant absorbs heat from the engine and transfers it to the radiator, where it is cooled by airflow or a fan. The cooled coolant is then circulated back to the engine, providing a more efficient and consistent cooling method.

Both air-cooled and water-cooled systems have their advantages and disadvantages. Air-cooled systems tend to be simpler, lighter, and require less maintenance, but they may be less effective at cooling the engine under heavy load or in hot weather conditions compared to water-cooled systems. Water-cooled systems are generally more efficient and provide better temperature control, but they are more complex and require periodic maintenance, such as coolant replacement.
