Here's a simple and inexpensive option from JP Cycles: http://www.jpcycles.com/product/720-976
I have used these on my last three Goldwings and like them because they actually are functional. They are thick enough that you can grip them with your knees. I have never had one come off, and I like that they are not so big they overpower the tank.
Just be sure you have them exactly where you want them, because once they are down, they're staying down!
