At what speed does the wind noise cancel out a factory fitted stereo on a bike ? I,m sure the Road /Street / Ultra Glide boys will know .

G'day Tim, Ivé only done 320klms so far on Tigger but have found out the wind does nothing as you are behind the screen area. You are in the slipstream area and the tunes just a keep on flowin.The stereo has an speed dependent volume increase to allow for road noise though. The Ultra is Surprisingly quiet and calm behind the big batwing with a full size screen. I suppose if you could lift your head up enough, the wind noise would take over then,  but ya don't need to do it on an armchair on wheels and ruin the ride!  Do yourself a favour  and go for a test ride on an ultra next time ya get time. You'll be amazed. I wish i got mine years ago now. Have fun. Hutch.

P.S. I may or may not have touched the ton, (accidentally of course)  to give you this informed answer!

 You have the upgraded version too Rider, so yours will sound even better than my standard affair which is more than adequate so far. Just don't let me hear yours too soon hey, I can't print money quick enuff!
