Front variator for the Honda Dio AF 34: a drive pulley with rollers. It changes the transmission ratio smoothly as engine speed rises. Manufacturer: DONCXIN.
Replace it if the rollers and guides are worn, acceleration is sluggish, or it vibrates and overheats. The condition of the variator also affects the belt, so check the belt too.
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.
