BMW Motorcycle Cooling Systems

BMW motorcycles are renowned for their superior engineering and performance. A key component to achieving optimal performance is the cooling system. A functionality of the BMW motorcycle that's designed to maintain engine temperatures preventing any chance for overheating. The cooling system works by circulating coolant through the engine, which absorbs all the heat generated during the combustion process.

Key Cooling System Parts for BMW & Triumph Motorcycles

The cooling system of a BMW motorcycle consists of several components. The radiator, water pump, thermostat, fan, and expansion tank. The radiator is the most visible component of the cooling system and is responsible for dissipating heat from the returning coolant that has cycled through the engine. The water pump is responsible for pumping this circulation of coolant. The thermostat is a temperature-sensitive valve that regulates the flow of coolant through the engine and radiator based on the engine's temperature.

The fan is another essential component of the BMW motorcycle cooling system. It is designed to cool the engine when the bike is stationary or moving at slow speeds. The fan is activated by a temperature sensor that detects when the engine reaches a certain high temperatures. The expansion tank is another important component of the BMW motorcycle cooling system. The expansion tank give the cooling system a "cushioned effect" which enables the warm coolant to expand which prevents the radiator system from being over-pressurized.
