TOP PERFORMANCES Piston Ø 46.20 (Manufacturer reference: PTA0079) is a replacement piston designed for 2T engines, intended for urban scooters and mopeds. Made from aluminum, it meets the maintenance needs of the top-end for a bore of Ø 46.20 mm. This part is suitable for interventions during an engine overhaul or when replacing a worn piston.
Compatible with several 50 cc scooters, this piston is particularly suitable for the following models: APRILIA SR 50 R FACTORY (2014), PIAGGIO ZIP 50 2T SP E2 (2013), and GILERA RUNNER 50 SP (2012).
