Description
CVT / Variator Yasuni Axial - Cutting edge technology by Yasuni
Yasuni is mostly known for their high-quality exhausts. We now also carry Yasuni’s innovative axial CVTs. The axial system was patented by Yasuni. The advantages of an axial design CVT are more direct power transmission and optimized delivery of power to the rear wheel. The new axial variator is CNC-machined and leads to a power increase of up to 25% in all rpm ranges.
- Patented axial system with fibre bush to reduce friction
- CNC-machined from 6000 series aluminium with ceramic coating
- Improved acceleration and higher top speed
- Long service life and low maintenance due to innovative low-wear sliding weights (“fingers”)
- Delivered pre-tuned for each model
Fits Sym Cruisym 125cc after 2018 / Joymax 125cc after 2021
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.
