CVT Variator OEM quality Piaggio MP3 / X9 125cc

scooter CVT

Modern scooters are equipped with a continuously variable transmission, the so-called CVT, also called variator.

CVT Parts:

• Front pulley, movable. It contains the variator weights and has a special shape with an inclined surface to allow the V-belt to move freely up and down.
• Ramp plate: Holds the weights in place.
• Variator sleeve: Serves as a bearing for the variator, which moves axially back and forth, i.e., opens and closes.
• CVT roller weights: Adjustment weights that play a critical role in function and performance.

original, Sport and Oversize CVTs

• Original: Original or OEM quality CVTs are equipped with a restrictor to limit the speed to 45km/h. There are riders who remove the restrictor to derestrict their scooter and unleash the full performance without restrictions.
• Sport: Sport CVTs are lighter than the original and are characterized by special angles and a special coating, which increases the top speed, but especially acceleration.
• Oversize: Based on the same principle as the Sport CVT, but has larger dimensions. With an oversize / overrange vario, the performance of the scooter can be increased even further.

You should also always replace the V-belt when replacing the CVT or go for a complete CVT kit.
