I own a 1300 and I'm doing extensive modifications. The speedometer isn't as much of a problem as the ignition switch is. (although the riser with integrated speedometer bracket limit you on new riser choices). Someone on Vstar 1300 Riders Forum posted that he had a Memphis shades batwing fairing (not sure about stereo) but he could get to the ignition switch but not easily. I actually moved my ignition switch because I'm mounting a tach right above where the switch used to be. For modification purposes, your going to find alot more accessories for the Roadstar and it's easier to modify. I bought my 1300 for specific reasons (water cooled, lighter, fuel injection, faster), but I am fabricating many of my own components to get the 1300 to look like I want it to look, more like a custom than a classic. That's not to say that you can't buy aftermarket parts for the 1300 (mostly touring and classic parts), just not as many as the Roadstar and not ones I wanted.
