Welcome to the best site for the Triumph Rocket and welcome from Virginia.
If you would please go back to your profile [person icon upper right of the screen - then Contact Details - then Personal Details] and add the year and model of your ride. And you've already asked the most common question, and the answers will depend on the year and model. And while you're there, please put a location.
As for mods, there are many many many, and you can start with my signature for some hints.
Almost anything you would want to do, someone here has done, and/or has a good idea about where to start.
