BMW Motorcycle Thermostats & Parts

Your BMW Motorrad motorcycle has a thermostat for a reason. While it only serves one purpose, that's an essential one. It helps ensure that your liquid-cooled engine doesn't get overheated in summer weather -- or freeze up in winter conditions.

Essentially, it's a valve that reacts to the temperature of the liquid flowing through your engine. When that temperature gets too hot, the valve opens to allow more liquid to circulate to the radiator -- which allows the liquid to cool back down to an ideal temperature. If the liquid's too cool, the valve remains closed so that the liquid remains in the engine until the engine's reached an optimal operating temperature.
