Came out this morning to ride the Piaggio Liberty, and found my new left add-on 3.75 inch mirror and extendo bracket lying on garage floor.
3M tape gave up. 2" >> 3.75" was too much for it.
At least it didn't drop off while in flight!
Heck with it!
Turns out, now that wearing the slimmer sleeved ICON leather jacket...I have acceptable vision behind me with the stock mirrors.
Ah me....
