COOLING SYSTEM
The radiator is mounted on the front left-hand side of the
mortorbike behind a protective grill. The radiators propose
is to maintain a constant engine 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 cir-
cuit 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.
