MAKE SURE THE MIRRORS ARE CONVEX!
MAKE SURE THE MIRRORS ARE CONVEX!
Yes, I said that twice on purpose. I bought a set of short mirrors for my 650R from Ninja650Shop (paid about $60 for them, it was my first mod), and the mirrors were not convex. Meaning, things looked A LOT closer than they should. If you don't get convex mirrors, then it will be damn near impossible to use them and they should be against DOT regulations if they are not already.
I still have them in the original packaging and never used them. I never even took them home from work, which is where I had them shipped. They are sitting on the shelf right over my desk...i'm looking at the little pieces of crap as I type.
