I like this mirror. I bought one to try on my GS500 before spending the money on 2 if I didn't like it. Good fit, and comes with different sized rubber sleeves to fit a variety of bar diameters. A minor issue, the finish is a bit fragile and scratches easily. Use care when mounting, a casual bump with the wrench can scratch off the black finish. The bigger issue for me is the mirror has two different fasteners. The bolt to adjust the arm is a nice recessed allen head that hides nicely in the design. The bolt that is tightened to squish the rubber donut to mount the mirror is a simple 6 sided bolt that sticks out and looks ugly. If they were both nice recessed fasteners I would have given more stars on fit/finish. Otherwise good clear view behind, glass doesn't rattle, and they can be adjusted into many different configurations. Good wide field of view, I'm glad to be rid of the stock, I would much rather have a clear view of my blind spot than my shoulders. I will buy another to match. If I feel motivated I may look for a better looking bolt for the mount. .
I installed these mirror on an 82 Seca 750. They installed easily and securely. The rear view with these mirrors is much better then stock! Images do not blur and with the mirrors on the ends of the bars, my field of view is much greater. Finally, they look great on the bike. Would buy again and recommend.
