If you have a trailer hitch, you can tow the scooter home, WITHOUT using a trailer. I towed a Honda 550-4 motorcycle 600 miles like this.
Rig up a way to lift the front wheel and attach it to the trailer hitch...lash it down tightly.
In my case, I removed the ball and replaced it with a short piece of steel channel that the wheel would sit into....then lashed it down.
Next, run stout ropes or lines one from each handle bar end to your luggage rack. Make them tight. If you do this right, this will secure the bike firmly in place.
Do a short test run and re-check everything to make sure nothing is slipping.
Take off for home....drive 55 or under. The back of the bike will lean as you turn and follow you where ever you go but the front wheel and and handle bars will not move.
I don't know if this is good or bad for the scooter engine and drive system. It was no problem for my Honda.
