Piaggio Cylinder Stud M8 x 160 mm for Vespa 160 GS / 180SS / Rally / PX200 / PE / Lusso / Cosa 200 for GILERA / PIAGGIO 125-180ccm 2T AC/LC
Cylinder stud bolts should be replaced as part of regular servicing or cylinder replacement. A turn of the screw and threads can be stripped anytime. It does well to change out regularly and better, an extra or two on hand.
Note: Although some cylinder studs have the same thread, they differ in their gradients. The studs are supposed to interlock with the crankcase. The nut will therefore only fit on one side. Sometimes this side is marked.
OEM numbers (for comparisons): 016058 – 0160586 (PIAGGIO)
