OEM Numbers (for the purpose of comparison) 133524 - 133068 (PIAGGIO), 133068 (LML). The PX flywheel side bearings are originally produced by NADELLA. Riders of the Vespa 160 GS/180 SS/180/200 Rally 1° models can sleep easier in the knowledge that the crankshaft bearing originating in the Vespa T5, also fits their scooter, so helping prevent engine breakdowns due to bearing failure!
