Aren't the lowers on your slower silver Connie black, and also quite a bit of trim bits black??
Yes. All the Concourses have flat black lower fairings. Except for black bikes, all Concourses have a non-black upper fairing. The canyons span over about half the lower and half the upper. So if you get black, it will half match and half not. If you get chrome or any similar color to your bike it will half match and half not.
In my case, I learned something that surprised me when I put the chrome rear bars on. Since the silver bike already has black lowers, dash, grips, seat, rear, and bag trim, but silver bags, pegs, exhaust, discs, and swing arms, and chrome headlight reflectors, heat shield, and discs, it looks quite decent. The mixture "works". I think it will work the same with the chrome front bars.
I think those with non-silver and non-black bikes are going to have the hardest time deciding what to do from a color standpoint. I have a feeling the chrome bars will only really work on a silver bike (and MAYBE a Neutron bike). For all others, black might be best, or perhaps color-matched.
