14.1 Cooling system
H01453-10
The water pump

in the engine forces the coolant to flow.
The pressure resulting from the warming of the cooling system is regulated by a valve
in the radiator cap

. This ensures that operating the vehicle at the specified coolant
temperature will not result in a risk of malfunctions.
120 °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 cool-
ing effect.
14.2 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.
