Buy a cheap V-belt for your scooter? During a major maintenance service you should always replace the V-belt. This is the drive of your scooter and therefore crucial. A V-belt has to endure a lot and therefore wears out quickly, but also dries out. If the V-belt breaks because it was replaced too late, you can get a lot of trouble. So be smart and replace it on time. Repairs are more expensive than maintenance.
