Rear variator assembly for the Honda Dio 18: a driven pulley with a clutch. It transmits torque from the belt to the rear wheel and provides a smooth start. Country of origin: China.
Replace it if it slips, jerks at start-up, vibrates, or the clutch friction linings are worn. It often has to be replaced together with the belt.
Parts are chosen by the model and the number in the name (Dio, Lead, Tact, and the version): dimensions can differ between versions, so check the part before installing it.
