welcome to the forum
usually a 2" hitch has a tongue weight (how much weight is on the hitch it's self) of 350 to 500 lbs. when you see the rating that's how much weight total you can tow. for example, a 10,000 rating could tow a 1,000lbs trailer with a 9,000lbs car or truck on it. you obviously dont want to go right to the limit as there are many variables to account for. i personally never go over 80% the raiting for safety.
they do make hitch platforms for scooters. no trailer needed. just account for your total weight and you should be fine.
