The DOPPLER ER2 centrifugal clutch pulley is the ultimate asset for your moped. It consists of a deep-drawn steel bell, a machined aluminium pulley and three clutch shoes. The advantages are undeniable: a higher engagement speed and therefore a more direct start, the possibility of fitting a direct drive variator (especially for MBK bikes) while guaranteeing the clutch function. A freewheel needle cage is integrated for starting.
