HI there I have an Aprillia Habana 125 custom 2003. I have removed the starter motor and bought a new one but I have forgotten which order the wiring goes back and I cannot find any diagrams online
In addition to my above answer, make sure you spell "Aprilia" correctly when searching, that will help get more results.. All the best and hope my suggestion helps.

My suggestion would be to search eBay for a similar but second hand starter motor and hopefully you will find one with the wiring still attached in the photos, as they are often sold like this.. Zoom in on the photo and hopefully you'll be able to match up your wiring.. Good luck
