The test drive is done...took some getting used to and adjusting on the fly at one point, at about 5 miles in, the bolt on the right side loosened and I got a great view of my shoulder until I could pull over and tighten it up. Looks like I'll have to check out that locktite stuff.
anyhow, I waspleased with the new position of the mirrors. I wear a full face helmet and glasses, and found I had to tilt my head down further than I felt comfortable with while riding. With the risers I can see the mirrors and not have totilt my head nearly as much. I would have preferred them to be even a little higher. It does give a wider angle view behind me. I am pleased with them so far.
