Recently bought one of these MRA screens for my 2017 (Model Year) SV650 AL7. Was easy to fit and is well constructed and fits in with bike well.

Worked well to keep windblast off chest but moved the air up to helmet area, both my Caberg Duke and AVG helmets suddenly changed from being pretty quiet to being hellishly noisy (had to use full strength foam earplugs, which I hate as they cut out 90% of all noise and make you feel as though you are in a bubble) - ended up chopping of the top 70mm or so (the upturned lip) which seemed to be causing disturbed air (vortexes / vortices ?) to form and bash into my head area. Still keeps a lot of air off me, hits me mid chest now (and nicely covers the instrument panel to keep sunlight and rain off). All I can say it is better than no screen but that top lip which looks OK was anything but. I have talked to others who also chopped the upturned lip off screen on their faired sportsbikes because of helmet wind noise. Both helmets were so quiet before screen fitted that I didn't need earplugs, apparently this is because the helmet was in a clear air-stream that was able to flow around helmet cleanly (as the helmet designer intended).

May just have screen on for colder months and take it off for summer riding. Attached photo is MRA screen minus the upturned 70mm lip
