Modern scooters and maxi scooters are equipped with an automatic transmission. At the heart of an automatic transmission is the actual variator / CVT. Gear ratio is adjusted automatically, it is infinitely and continuously variable. The underlying principle is simple centrifugal force. CVTs are composed of the variator unit with roller tracks, sleeve / boss, ramp plate, sliders and the weights.
Our range includes many CVTs in OEM quality for scooters with Minarelli, Piaggio, Peugeot, GY6 or China 2-stroke engine.
For tuning set-ups we recommend a performance-enhancing sport or tuning variator from manufacturers like:
And if you want to take it a bit further, you should get an oversize / overrange CVT from Malossi or Stage6.
