What is the top speed of Aprilia SR 125?

The 125 model has to be accelerated fast before even climbing a hill. I usually climb hill with a pillion. usually I have to accelerate very hard and keep a fast speed while climbing a steep hill. If you fail to acce;erate hard and maintain a fast speed your scooter will stop half way and go backwards which can be dangerous. I have fallen 3 times because of acceleration with a pillion. This scooter is not appropriate for a hill climb with a pillion. A single rider is allright though it cannot keep pace with the 100-110 cc's on hill climbs. It's good only for snake pattern hills and plains for cornering and for ripping only. Rest you cannot expect hill climb miracles!I am riding since 2 and half years. The initial is very low. Even on plains it struggles or makes too much noise when starting to move.

If the service is in the authorized service center then its maintenance will be resonable or else it is too much.
