Description

GY6 CVT

Inexpensive complete variator in original part quality. The CVT is supplied as shown with variator, ramp plate, pulley, fan wheel, sliders, star pulley and CVT weights measuring 16x13mm.

The original CVT sleeve from the vehicle can still be used, but should be cleaned before fitting. You can also order any variator sleeve separately.

A new variator is recommended if acceleration issues occur due to a worn bushing causing the variator to jam, or if the variator shows signs of wear, such as grooves on the V-belt running surface.

Note: The CVT is supplied with quite heavy weights (approx. 8.3 g). We recommend the use of lighter variator weights in order to improve torque and response.

Notes and Safety

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.
