COOLING SYSTEM
The radiator is mounted on the front
right-hand side of the mortorbike
behind a protective grill. The radiators
propose is to maintain a constant engi-
ne temperature by cooling the hot
water which is pumped around the
engine.
To check the level of coolant, carefully
undo the radiator cap off and top up
if necessary.
NOTE: never open the top of the radiator when the motor is hot, because the boiling liquid could
escape under the pressure, which is dangerous.
It is strongly recommended that you use a closed circuit anti-freeze liquid. In this way we can
avoid the water freezing causing damage to the water pump and water pipe ruptures. Do not top
up with tap water as the calcium content could damage the radiator.
