Notes and Safety 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.

You can then remove the worn V-belt and replace it with the new one. When
