I really really like the look of the V&H Shotshots. I know they "rob you of (high-end)power", but don't you gain low end torque in replace? I've looked at my friend's XL with Shortshots and the only thing that I can see that would possibly cause a problem would be the tension sprocket getting in the way of one of the mounting brackets, which could easily be fixed with a custom one. Other than these two "disadvantages", which one of them can be clammed as advantage if you like low end torque, what am I missing? Oh and possibly the rear break "pedal" might touch it, which could also be fixed. Why doesn't anyone make a set that looks like these, that would mount onto an XR?
