The auxiliary shaft bearing of the Vespa GS160 (GS4) / SS180 models differs significantly from those of the other large-volume Vespa engines, such as the Rally180.
AI-translation
The GS160/SS180 has been designed much more robust and complex with a large needle bearing cage mounted on the outside of the kick starter pinion tread. Thus the circulation speed is clearly reduced as well as the bearing surface is considerably larger than in Rally and Co.
The bearing consists of several individual parts and was not available for a long time.
We now offer not only a completely newly reproduced bearing "Made in Italy" but also the individual needle bearing.
