BMW Motorcycle Cooling Systems

A motorcycle's cooling system exists to regulate the temperature of your vehicle's combustion, ensuring an efficiently-running engine throughout your drive. Without the cooling system, your engines would require a lot more fuel to function, eventually reducing your gas mileage quite significantly.

The two main parts of a motorcycle's cooling system are the thermostat and the water pump. The thermostat is responsible for determining how much coolant should pass through the water pumps, and then the engine.

Meanwhile, the oil cooler and expansion tank function relatively the same, only for different substances. True to its name, the oil cooler is designed to regulate the temperature of the oil that flows through the engine, while the expansion tank is what allows the expansion and contraction of the coolant as the engine cools up and down. The fans also help cool the radiator down in case it gets too hot.
