PIAGGIO LIBERTY 125 S 2026 Test Gearbox problems functionality
The transmission layout includes an automatic speed variator and a dry centrifugal automatic clutch, paired with a final gear transmission in an oil bath. During intensive stop-and-go usage in city traffic, the clutch maintains linear engagement. However, a slight metallic squeak from the drive belt can be noted during cold starts, a phenomenon that disappears as soon as the transmission reaches optimal operating temperature. No anomalous slipping or clutch grabbing was recorded, indicating good ventilation of the transmission casing.
