Front half-pulley -KB-Racing- Piaggio 125-200 ccm Leader

Tuning Part Made In Germany! The toothing for the oil pump pinion is eroded into the pulley. Afterwards the oil pump pinion is pressed into the pulley by interference fit to be planned in the lathe.
Thanks to the massively reinforced gearing in the pulley the impact of the starter cannot mess up the gearing on the crankshaft anymore.
Eminently recommendable for tuned engines.
