The mirrors are smaller than they look which is a good and bad thing. They vibrate alot but thats understandable just remember to use loc-tite on mounting bolts or they'll come loose. Great looking mirrors.
These mirrors were easy to install - I did not need the suggested adaptor. I would have liked them to be a bit taller, but I adjusted my grips down and now can see just fine. The mirrors themselves are larger than I expected, which was a good thing since my previous mirrors were very small.
