Thanks everyone. One of the problems i have is visualizing, since my bike color/scheme is very rare.I've only seen 1 other rkc like mine.And what looks like black on my bike is actually depending on the light appears dk green w/burgundy flakes especially the fender.

 

I vote 21's for sure.....

I also think fat spokes and a thin whitewall tire look awesome on a classic.

 

Either or, it will look a lot nicer with a custom wheel. I do like the contrast, they do run more $ though, from what I have seen. +1 on HogPro they are awesome, bought from them, great service.
Good Luck, you will make the right decision, that is why we call it customizing.

 

if you want black shinny , they do black chromed

 

+1. I totally agree with your take on contrast cut wheels. Chrome is the way to go. Both the 18" and 21" wheel would look good. I personally like the 21" up front on touring bikes, though.
