Welcome to Florida.
I added the
Florida laws to the wiki. It includes links to the various websites also. If you have anything over 50cc, it will be the same as a motorcycle.
If you have a motorcycle endorsement on your PR license, you should not have to take any test, other than an eye test in FL. At least I didn't from NJ. Not sure how they treat PR, but it should be the same. If you don't have a license, you are going to have to take a course.
If you are bringing your vehicles with you, be prepared for an impact fee. It is applied to all vehicles the first time they are registered in FL. I think it may be different for each vehicle, but check their
website for the specifics. I had to pay it for all of mine. Can't remember if it was $100 or $200 per vehicle.
Let me know if you need anything you can't find in the wiki or on these sites.
