The original Piaggio disc springs (half-moon wedges) are characterized by a production deviating from the DIN standard. The disc springs have considerably larger radii and thus make installation much easier: A Woodruff key is not designed to transmit driving forces. The frictional connection between the two components is established via the tightening torque and a cone.
Does not fit Peugeot, Honda or Vespa Rally180 / Rally200 with Femsatronic ignition.
