Water-cooled motor cycle engine has a ribbed hose to carry the hot coolant from the engine back to the radiator and reduce its temperature before it reaches the radiator

The cooling system for the water-cooled engine of a motor cycle has a coolant circuit through a radiator (1). At least one cooling ribbed hose (2), of a material with good thermal conductivity, is downstream of the motor and in front of the radiator (1) to carry the hot coolant fluid from the motor, and reduce the coolant temperature before it reaches the radiator.
