Description
WE carry spare parts for 4-stroke scooters as well: Polini Variator for Yamaha Giggle / Zuma (and corresponding MBK models).
As it was developed to be used with the original torque drive, it has a "small" outside diameter and has to be used with a standard (preferably reinforced) drive belt. The angles of mobile pulley and ramp plate were designed to improve acceleration. Top speed will be increased as well - 10 - 20 km/h more than with the stock variator.
- Included: 16x13mm à 4.9g.

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.
