Drive Belt Evolution Aramid Belt from Polini
High quality drive belt from Polini. The V-belts are reinforced with aramid fibers to make them extremely tear-resistant and much more durable than standard V-belts. The Polini Aramid drive belts withstand much greater loads and speeds without any problems. Fatigue and wear are reduced, reinforced belts are extremely stable even at high temperatures. Due to the belt's increased elasticity, the optimal operation of the transmission is guaranteed at all times.
The premium V-belts from Polini are the perfect choice for racing, but can also be used in everyday life or in original setups.
Note: Drive belts should always fit properly. Belts that are too narrow and therefore sit too low reduce top speed, belts that are too wide and sit too high lead to power gaps when starting and belts that are too long have too little tension, which has a negative effect on power transmission.
We recommend to replace the V-belt regularly to ensure optimal transmission of power. Maintenance intervals vary depending on the model, general guideline is 6,000 to 8,000 km for 50cc scooters and 15,000 km (and more) for maxi scooters.

When to change the V-belt?
On scooters, the engine power is transmitted to the rear wheel via the V-belt or drive belt, which connects the CVT variator to the torque drive. As a rule, it should be replaced every 10,000 to 20,000 km. The belt slips when it is heavily worn. By the way, a new belt also slips and needs a short run-in period.
How to change the drive belt?
Replacing the V-belt is a relatively easy, you don't need advanced technical know-how. The first step is to remove the variator cover to get to the variator. You'll need a piston stopper and a blocking tool to remove the CVT and clutch bell. You can then remove the worn V-belt and replace it with the new one. When reassembling, make sure that the V-belt is properly seated and has the correct tension.
