You made it to the website to learn a lot about the VTX bikes. Both the 1300 and 1800 offer comfortable rides. The 1800 is by far the power beast and might be more of what you are looking for. I think far too many people try to make them into something they were never intended to be. If you want a rocket, a street bike is much more likely to satisfy a need for speed.Ok so there is a way to upgrade. Im sorry for my lack of knowledge but again I am a street bike guy. Is there a website I can got to, to learn more?
