The drive belt for 2-stroke Piaggio/Gilera 50 scooters transmits torque from the front variator pulley to the clutch and the rear wheel.
- Replace it if it shows cracks, delamination, or heavy sidewall wear, if it slips during acceleration, or if top speed drops.
- Before buying, check the markings on the old belt (length and width) and the scooter model.
When replacing it, inspect the variator rollers and the pulley faces: their wear shortens the life of the new belt.
