I bought a C/B windscreen and mounted it this spring. The screen is +4" h, +2" w, non flip. The screen is a vast improvment over the std. screen, but still allows buffeting & wind noise.
Last week I was prepping a '93 Guzzi SPIII to put up for sale. It had a Saeng-ta Stealth edging on it. I'm not 100% sure, but believe the micro-swirl and stealth edgings are one and the same product (a quick call could let one know). As I'm selling the Guzzi, I put the Edging on the FJR to try it out.
After using this combination for about 300 miles, I would report that it is again a vast improvment . Almost to the same degree as is the C/B over stock. Much reduced wind noise and buffeting no matter what position the screen is set at.
This seems to be a very subjective consideration so I can't say how this combination may affect another individual, but it sure does work for me.
For reference: the FJR is an '05: I'm 6' w/ 34" inseam.
P.S. The Can Do cleaner/waxer product they sell is easily the best product of it's type I've ever had the pleasure to use.
Hope this helps, JC
