motorcycle and scooter Water pump

The water pump is a crucial component of a liquid-cooled engine. It ensures that the coolant circulates between the engine and radiator to prevent engine damage from overheating.

For scooters, motorcycles and mopeds, there are repair kits for the original water pump, but also water pumps with increased flow (for tuned engines or for intensive racing use) and electric water pumps.

Electric water pumps are especially popular with tuners, as they eliminate a mechanically driven element and thus relieve the engine of an additional load, resulting in a slight increase in performance.
