Quality Guarantee 15mm*12mm Clutch Variator Roller for scooter
♥100% brand new high quality product.
♥Best Feedback from Customer, we always ensure 100% customer's satisfaction.
♥Package: 1set, 6Pcs.
♥Tips:
Lighter rollers weights require higher RPMs to push the rollers outward through centrifugal force and begin changing your CVT's gear ratio.
Heavier roller weights need lower RPMs to begin changing gear ratios.
Lighter roller weights = faster take-off acceleration, lower top speed.
Heavier roller weights = slower take-off acceleration, higher top speed.
For stop-and-go city driving, lighter roller weights may be preferred.
For long-distance highway driving, heavier roller weights may be preferred.

On modern twist and go scooters, a variator drive system gives the optimum gear ratio between the engine and the rear wheel. This enables the engine to work at the best RPM in comparison to road speed and conditions.
The variator works upon the ratio of the diameter of the front and rear drive belt pulleys. Both front and rear pulleys are an assembly of moving plates.
Behind the moving plate of the front pulley, there are clutch rollers. These are thrown towards the outside edge of the variator by centrifugal force, as the rotation speed of the engine / variator increases.
[Rollers]
When the weight rollers move towards the outside of the variator, the inside plate is forced together with the outer plate and this moves the drive belt towards the outside of the pulley. This effectively makes the diameter of the front pulley larger. As the belt moves out on the front pulley, the tension in the belt is increased, which overcomes the spring pressure holding the two plates together in the rear pulley. The belt moves towards the centre of the rear pulley, which effectively makes the diameter of the rear pulley smaller. In this way, the ratio between the two pulleys is changed and therefore, the speed ratio between the engine and rear wheel is changed.
It is common for the scooter manufacturers to restrict the speed of the scooter by fitting a spacer washer under the variator. This restricts the amount the variator is allowed to open. if removed the belt is allowed to go further out into the pulley.
