I love mine. Had it on my R3R for almost all of my 23000K miles. I would caution you about the brackets though. I believe they are aluminum, not stainless. I suspect this because my brackets broke at about the 15000K mile point. I suspect from the vibration and flexing due to constant wind. It actually broke off on a freeway interchange while I was stuck in traffic going about 5 mph. That was lucky. As soon as I heard something dragging, I stopped, figured out it was the chin spoiler and yanked it off the other mount with not much convincing. I stuck it in my saddle bag and took it home.
I suggest you do what I did and get some steel straps, use the original backets as templates, and cut you some stronger brackets. Go ahead and paint them while you're at it. You will have to attach the brackets to the spoiler with nuts and the original bolts then mount it on the bike. The original has nuts built into the strap, so it wasn't necessary. I'd suggest making new brackets now since once they break, they are much more dificult to be used as templates.
I happend to have some angled brackets that I pounded flat and drilled holes, but if I were to do it again, I'd go get 1/32" sheet and cut them out.
