I felt I just can´t leave you here to read about scooters. If you want to build a nice one, go to Omars. There you will find anything apart from the XS650 itself.
First you need a seat, and a new set of rims, a new tank, and a side mounted tail light and a few more things later And you might end up with something like this. Them Belladonna trackers are pretty right you know. These bikes rules.
