Why? And which Vespa

If you want a bigger throttle body on a gts 300 then I know you can get the 38mm version from a Piaggio Beverly 350 and use that. There are some on vespaforum.de who have done this.

For the GTS HPE if you want to tweak the engine mapping the you can use something like

Malossi Forcemaster 3 https://www.malossistore.com/en/it/force-master-3-electronic-controller-for-injection-vehicles-vespa-gts-hpe-300-ie-4t-lc-euro-5-2021-2022-md31m-5519335-vehpe30021-M-P

TFC Smart ECU https://www.tfc-drag-racing.com.tw/en/product_description.php?PNo=763

and for a 125/150 Sprint / Primavera

Malossi Forcemaster 2
