Backstory: My wife and I are in Paris for a week (this week) and looking to travel around and see the sites, are we in district 14 and looking at some of the site's we want to see are all best traveled (seemingly) by car/moto. I have had my Motorcycle license in the states for 8 Years.

Question: What is required to rent a scooter/motorcycle in France (Paris) and what are the dangers? I've seen a lot of information online stating number of scooters stolen (1 Every 5 Minutes). Should I taxi instead or use the train? It seems scooters are cheaper if we can both ride one together. What is required to ride with a passenger?

Thank You!
