Drive Belt Polini Original Yamaha Aerox / BW's

Polini Original

The "Original" exhaust from Polini is an inconspicuous exhaust that looks very similar to the original exhaust, hence the name.

As always with Polini, however, you can rely on very high quality, and the Original also offers limited volume and slightly increased power. These exhausts are ideal as a replacement for the original models and are homologated (road-legal).

Attention: this type of OEM quality exhaust cannot be used with racing cylinders!

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.
