Cooling system

Water pump 1 in the engine ensures forced circulation of the coolant.

The pressure resulting from the warming of the cooling system is regulated by a valve in radiator cap 2. Heat expansion causes excess coolant to flow into compensating tank 3. When the temperature falls, this surplus coolant is sucked back into the cooling system. This ensures that operating the vehicle at the specified coolant temperature will not result in a risk of malfunctions.

110 ºC (230 ºF)

Cooling system

The coolant is cooled by the air stream and a radiator fan 4, which is activated at high temperature.

The lower the speed, the less the cooling effect. Dirty cooling fins also reduce the cooling effect.

Info

If the cooling system overheats, the maximum engine speed is limited.

Note Damage to reflector Grease on the reflector reduces the brightness. Grease on the bulb will evaporate due to the heat and be deposited on the reflector. Clean and degrease the bulbs before mounting. Do not touch the bulbs with your bare hands. Remove the screw on the rear of the turn signal housing. Carefully remove diffuser 1. Push bulb 2 lightly into the socket, turn approx. 30º counterclockwise, and pull it out of the socket.

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 components of the cooling system. In the event of scalding, rinse the area affected immediately with lukewarm water.
