by the looks of that it fits on rear seat pin and the plate goes under your rear light. Lots of holes so am assuming it is a multi model item.
This is fine if you are going to keep it on the scoot all the time (imho it will spoil the look of the curvy rear end) and a pain if you only want to put it on occasionally as you will have to remove the rear light every time.
Pretty certain you can get ones that have arms that come down to attach to the numberplate mount, though you might have to search a bit for them, and can't remember if I saw them or if it was front carrier but something that had rubber sucker type feet that rested on the bubbles and attached to rear seat pin.
We don't own this planet, we are only borrowing it from our children. How would you like to give it back to them?
