Chip,
1. What is the width of those bars compared to the stock bar? (Not counting the mirrors or bar end weights)
725 mm
2. Did you have any trouble with your bar controls hitting the gas tank at full lock?
Nope! none at all
3. Hollow aluminum or solid?
hollow but they have a thick wall, 14mm internal diameter
4. Did you have to shim the bars or bar controls to get everything tight when you installed them?
no shimming needed. just had to drill the holes for the controls to lock into. (measure and test prior to drilling)
5. Bar vibration the same, better, or worse than stock?
Vibration is a bit better to be honest. My stance has changed so I put more weight on my hands (because I'm leaning forward more, which I love)
6. (Last one I promise) Your source, model #, and price?
They are Renthal Road Ultra Low Bars. I paid $52 for them. They come in satin aluminum (what I have), satin gold ( another member on here has them) and black ( not sure if they are satin on gloss)
Part # 758-01
I got them from Amazon.com Search for Renthal Ultra Low Road Bars
