I wasn't sure about getting these when I bought my batwing fairing, but am glad I did. They are great for diverting cold air in the winter, rain in the summer, etc. They are just the right size to divert air and debris, while still keeping a nice appearance for the fairing.
I bought this even though the Dk website said it would not fit and the pictures I found online looked as though it would be 50/50. I figured for the money, I could make it fit. There were no issues installing. It went on just like it was supposed to without any interference from the signal lights. Overall it does add a nice look to the Batwing.
I put about 2000 mikes on my Stryker with the the fairing on it. The stock fairing pushed most of the air down on my knees and feet. With the additional parts I just feel the wind on my shoes. Great addition to the fairing.
The lowers do their job as they are supposed to. The only thing I didn't like was the plastic screws that came with the lower fairings. I replaced all the hardware on the Memphis shades batwing with stainless steel metric bolts and lock nuts from Fastenal for a few dollars. Definitely worth a hardware upgrade.
A inexpensive upgrade for your Memphis Shades batwing really helps reduce the amount of air that passes around the fairing. The fit-n-finish could be better, I had to open some of the mounting holes a little as only a few lined up with the holes in the fairing.
