125/150cc scooters
This class of scooters is better than the 50cc scooter class. The 125/150 scooters are mainly for those with the need for speed. They have a mileage of 80-90 kmh (45-55mph). Even though the speed is relatively high than the 50cc scooters, brands such as Vespa, Tao tao, Qingqi, Piaggio, Aprilia, Bajaj and other leading manufacturers have made sure that you stay safe on the road by making them easier to control even at high speeds.

The 4 stroke engines are efficient, consume less fuel, and are reliable and they run quietly. You do not have to worry about those annoying engine sounds with a 4 stroke 125/150cc scooter. In terms of durability, the 4 stroke scooters in this class last longer.
The repair and upgrades for the 125/150 scooters are also easy to find.
