starter clutch 13mm Naraku racing heavy duty for Minarelli NK901.13

Reinforced starter motor freewheel without starter sprocket, from Naraku. The starter mechanism is subjected to higher loading where engines have higher compression. The starter motor freewheel has a metal securing ring (see image 2) and this prevents the winder drum from coming off the clutch. This ring should be removed before fitting the starter sprocket!
