As others have said all of the Harley's have ample power. And if you're going to be riding with others, you will all be riding at about the same speeds
If you have the need to be always out running the group then you need something else other than a Harley.
Try a Boss Hog. It's a bike with a Chevy 350 for an engine. Then you can be all by yourself in the distance or splattered against the back end of that semi way up there (hopefully not)
Enjoy your new bike. And ride safely.
