I'm always ready to add some do da to this bike to make it more to my liking and these sound pretty good. Today took a ride and using my hand I could not feel any air flow to amount to much coming under the rearviews. I also do not experience any turbulence at all with this Mastad so having a problem justifying the purchase. No wind problem to solve but maybe as Taxfree says it could put some cooling air onto me in the summer time, that would be welcome when the temps are in the 90s here. I will reevaluate when the weather gets warmer.
