Gearbox type:
A CVT (continuously variable transmission) is theoretically the best-performing type of transmission with an unspecified number of ratios that change smoothly without jerking. It perfectly adjusts the gear range to the load of the engine at any given moment.
Motor orientation:
The engine is in the horizontal position which means that the piston works horizontally and not in the up-down direction. Engines in this configuration are reliable and have low fuel consumption.
Output shaft length:
The short output shaft means that the engine is suitable for scooters with a single rear shock.
