If you own air wings (I have an RT but I think this will work on a RS) you may know they are great for helping keep the cold wind from blowing on you in the winter. However there is a large gap between the bike and the air wing. During the summer its not a big deal but in the winter you can really feel the air entering into that gap. The trick is to switch out the right and left top air wing, you will not be able to open and close them till you rotate them back but in the winter who wants them open? Anyway by switching the two sides you reduce the gap by about 75% and drops the cold wind down to almost nothing. Give it a try.
