Aprilia Threaded Mirror Mounts

I purchased these from AF1 racing for my 2017 Tuono. Very easy to install and fit perfectly. On one side I mounted CRG blindsight mirror with no problem. HOWEVER, on the other side when I tried mounting the CRG Hindsight mirror (larger, w/ thicker/wider bar clamp) it wouldn't fit in the groove. I used a file to remove material on both sides of the mirror recess and managed to wedge the bar clamp in, and finish seating it by torquing the pieces down and thereby pulling them together. What should've taken 5 minutes, took an hour and a lot of filing. A dremel would've sped up the process but would still have been tough. Lastly, due to weighing significantly less than stock bar-end weights, there's a stronger buzz in my handlebars. It's not super noticeable at first, but my hands got tingly after a short, fast paced, high-revving, spirited blast through some canyons. I'm talkin 14-15 minutes. That's NEVER happened to me on this bike. So I will have to put the stock weights back on for the track. Probably would've anyway, since mirror removal on one side would be equally or more difficult. So, I wish they weighed the same as stock, and I wish the mirror recess was properly sized for any CRG or similar mirror. But all in all, they do what I wanted, which is allow for a screw-in solution to bar-end mirrors on my Tuono. 3.5 out of 5 stars. If the mirror had fit, 4.5 out of 5. If you don't mind the small blindsight mirror on both sides, these will work very well for your Tuono or rsv4.
