Cooling system

Checking antifreeze and coolant level

Warning
Danger of scalding The coolant gets very hot when the motorcycle is driven and is under high pressure.
Do not open the radiator, radiator hoses or other cooling system components when the engine is hot. Allow the engine and
cooling system to cool down. If you scald yourself, hold the affected area under cold water immediately.
Warning
Danger of poisoning Coolants are poisonous and a health hazard.
Avoid contact between coolants and skin, eyes and clothing. If fuel gets into your eyes, rinse immediately with water and
contact a doctor. Wash affected skin areas immediately with soap and water. If coolant is swallowed, contact a doctor im-
mediately. Change clothes that have come into contact with coolants. Keep coolants out of the reach of children.
Check parts for damage and wear. Replace damaged or worn parts.
Position the fuel tank and fit the two spoilers to the side of the radiator fixing.
Make sure that no cables or Bowden cables are trapped or damaged.
