in the engine circulates the coolant.
The water flow through the radiator is controlled as a function of the coolant temper
ature. The cooling system is divided into two circuits. In the warming-up phase of the
engine, the coolant flows through the small cooling circuit. This heats up the engine
quickly. The thermostat

warms up and opens the opening to the radiator (large
cooling circuit). This keeps the engine temperature constant.
The pressure resulting from the warming of the cooling system is regulated by a valve
in radiator cap
@).
This ensures that operating the vehicle at the specified coolant
temperature will not result in a risk of malfunctions.
1120 °C (248 °F)
Cooling is effected by the air stream.
The lower the speed, the less the cooling effect. Dirty cooling fins also reduce the
cooling effect.
The radiator fan provides extra cooling. It is controlled by a thermoswitch.
Checking the antifreeze and coolant level
Warning
Danger of scalding
During motorcycle operation, the coolant gets very hot and is under pressure.
Do not open the radiator, the radiator hoses or other cooling system components if the engine or the cooling system are
at operating temperature.
- Allow the cooling system and the engine to cool down before you open the radiator, the radiator hoses or other compo
nents of the cooling system.
In the event of scalding, rinse the area affected immediately with lukewarm water.
Warning
Danger of poisoning
Coolant is toxic and a health hazard.
Keep coolant out of the reach of children.
Do not allow coolant to come into contact with the skin, the eyes and clothing.
- Consult a doctor immediately if coolant is swallowed.
Rinse the affected area immediately with plenty of water in the event of contact with the skin.
Rinse eyes thoroughly with water and consult a doctor immediately if coolant gets into the eyes.
- Change clothing if coolant spills onto your clothing.

Condition
The engine is cold.
Stand the motorcycle upright on a horizontal surface.
Remove the radiator cap.
Check the antifreeze in the coolant.
1 -25 ... -45 °C (-13 ... -49 °F)
If the antifreeze in the coolant does not match the specified value:
- Correct the antifreeze in the coolant.
Check the coolant level in the radiator.
