GENERAL INFORMATION
Check coolant level before each ride and every 1500 km (932 mi), see
see 5.2.1.
Coolant mixture is a 50% solution of water and anti-freeze. This is the ideal solution for most operating temperatures and
provides good corrosion protection.
This solution is also suited to the warm season, as it is less prone to evaporative loss and will reduce the need for top-
ups.
In addition, less water evaporation means fewer minerals salts depositing in the radiator, which helps preserve the
efficiency of the cooling system.
When temperature drops below zero degrees centigrade, check the cooling system frequently and add more anti-freeze
(up to 60% maximum) to the solution.
Use distilled water in the coolant mixture. Tap water will damage the engine.
(Recommended) engine anti-freeze, see
Refer to the chart given below and add water with the quantity of anti-freeze to obtain a solution with the desired freezing
point:
Freezing point °C
-20°
-30°
-40°
NOTE Coolants have different specifications. The protection degree is written on the label.
WARNING
Use nitrate-free coolant only, with a protection until at least -35°C.
DRIVE CHAIN
Check drive chain operation, slack and lubrication at regular intervals, see
The vehicle is equipped with an endless chain with a joint link.
WARNING
If too slack, the chain can come off the front or rear sprockets thus leading to serious accidents and
damage to the vehicle, with consequent serious personal injury or death.
Do not use the vehicle if the chain tension has not been correctly adjusted.
To check chain, take it with your hand where it turns on the rear sprocket and pull it as to separate it
from the crown itself.
If you can move the chain apart of the front sprocket for more than 3 mm (0.125 in), change chain,
crown and pinion.
DANGER
If not properly maintained, chain can early wear out and lead to the damage of both crown and pinion.
Perform chain maintenance operations more frequently if the vehicle is used on rainy or dusty areas.
TYRES
WARNING
If tyres are excessively inflated, the vehicle will be hard and uneasy to ride, thus making you feel not at
your ease.
In addition the roadworthiness, mainly on wet surfaces and during cornering, will be impaired.
Flat tyres (insufficient pressure) can slip on the rim and make you lose the control of the vehicle.
In this case too, both vehicle roadworthiness, maneuverability and brake efficiency will be impaired.
Tyres changing, repair, maintenance and balancing must be carried out by specialized technicians
using suitable equipment.
When new, tyres can have a thin slippery protective coating. Drive carefully for the first kilometers
(miles). Never use rubber treating substances on tyres.
In particular, avoid contact with fluid fuels, leading to a rapid wear.
In case of contact with oil or fuel, do not clean but change tyres.
DANGER
Some of the factory-assembled tyres of this vehicle are provided with wear indicators.
There are several kinds of wear indicators.
For more information on how to check the wear, contact your Dealer.
Visually check if the tyres are worn and in this case have them changed.
If a tyre deflates while driving, stop immediately.
Avoid hard brakings or moves and do not close throttles too abruptly.
Slowly close throttle grip, move to the edge of the road and make use of the engine brake to slow down
until coming to a halt.
Failure to comply with these recommendations can lead to serious accidents and consequent personal
injuries or death.
Do not install tyres with air tube on rims for tubeless tyres and viceversa.
