Aluminium pulley with integrated clutch with 3 clutch shoes. Mounting a racing variator on your moped can, depending on model, mean that you cannot use the clutch any longer. This special ER2 clutch pulley by Doppler will bring it back; to be specific, the clutch is integrated in the pulley.
For MBK 51 mopeds with racing variators / variators without clutch function.
