Description
Racing CVT NARAKU for Kymco 125 and 200i engines. The set consists of base pulley, ramp plate, sliders, CNC-machined outer pulley and two sets of CVT weights. The CVT leads to significantly improved acceleration and the maximum speed is increased. The set includes a set of 10.3g CVT rollers for more aggressive acceleration and another set of 11.5g rollers (18x14 mm). With the heavier set, acceleration is slightly lower, but the top speed is increased and the rpm is lowered slightly.

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.
