No the actual OEM plates. 2 bolts on the side and the one in the middle. I stripped the middle one and can't get the arm of the mirror off. I need the OEM plate to screw on a CRC mirror. They use a double sided bolt, 1 into the mirrors arm and the other screws into the OEM plate.
There is also a place to mount mirrors on the handlebars above the clutch and brake levers, the same way cb300f mirrors are mounted. There is what looks like a big black screw in the holes, but it's just a plastic plug you pry off with a knife. Your windscreen will probably be in the way though.
