Automatic transmission (02_18)
To ensure simple, pleasurable riding, the vehicle is equipped with automatic trans-
mission with regulator and centrifugal clutch. The system is designed to give the best
possible performance in terms of both acceleration and consumption, on level ground
and uphill, thanks to the adjustments made to engine speed and transmitted torque.
If you have to stop on an uphill slope (traffic lights, traffic jam, etc.) only use the brake
to keep the vehicle still, leaving the motor running at idling speed. Using the motor to
keep the vehicle still can cause the clutch to overheat. This problem is due to the
friction of the clutch parts on the clutch bell. It is therefore recommended to avoid
conditions of prolonged clutch slippage leading to clutch overheating (for example, as
well as the situation described above, riding uphill fully laden on steep slopes or start-
ing off on slopes greater than 25%, etc.):
1. Do not continue riding in such conditions.
2. Let the clutch cool down with the motor at idling speed for a few minutes

Safe driving (02_19)
Some simple tips are provided below that will enable you to use your vehicle on a daily
basis in greater safety and peace of mind. Your skill and your mechanical knowledge
are the basis of a safe ride. We recommend trying out the vehicle in traffic - free zones,
in order to acquire a good knowledge of the vehicle it self.
1. Before riding off, remember to put the helmet on and fasten it correctly.
2. Reduce speed on rough roads and ride with care.
3. After riding on a long stretch of wet road without using the brakes, braking can be
poor at the beginning. In these conditions, it is a good idea to apply the brakes from
time to time.
4. Do not brake hard on wet, unsurfaced or slippery roads.
5. Avoid riding off by mounting the scooter when it is resting on its support. In any
case, in order to avoid abrupt departures, the rear wheel should not be turning when
in comes into contact with the ground.
