New item to come in are these reinforced 9 Ball Bearings used on the Clutch Side of most Vespa models but also used on the Flywheel Side on Vespa GS/SS & other early models. These are made by FAG so quality is spot on, they take an extra ball (9 balls in total) and feel very smooth. These are priced at £16.50 giving the SIP version a run for their money.
You find these in the Vespa Crank/Clutch Section:
