Variator kit for Kymco AK 550cc JCosta XRP complete with Kevlar belt and specially designed crankshaft washer.
With the J.Costa XRP variator for Kymco AK 550 you will improve the performance of your motorbike and transform it into something you never imagined.
It is the most radical Kymco AK 550 variator on the market, offering power and reliability.
The new series of XRP variators (XTREME RACING PARTS) differs from the previous ones due to the presence of heat sinks inside the circle-shaped variator with protrusions between the mass area and the bushing area.
The cavities of the masses are drilled so that the pressure-depression effect makes them act more quickly and more smoothly both when entering a higher gear and when exiting a lower gear without skipping, i.e. to exploit the air as a dynamic fluid to help the masses emerge or be collected more quickly without increasing fuel consumption.
We have improved:
- Smoother operation.
- Lower temperature inside the drive, thanks to the revolutionary heat sink design
We receive:
- Faster operation
- A greater reaction to the Gas Punch, thanks to the Mass Pressure - Depression® effect.
