Congrats on the new bike. The fuel injection system is easily remapped, so to speak. Triumph left a lot of HP in there. Unlocking it is a pretty quick process. Beyond that, you can do cams and higher compression pistons and get a lot of HP out of it.
I had the Original VMAX from one it first came out. The Rocket is a more gentlemanly version hooligan bike. You don't have to rev it to the moon to make it go. The early ones don't handle as nicely (and are a lot heavier) than the current generation that came out with the 2020 models. If you exercise the torque, you will eat rear tires.
