I was actually looking at the Cobra saddle supports the other night. I've been contemplating on putting supports on for my throw overs. Let me know how the installation goes and how it works out for you.
My uncle has a Volusia, and he doesn't even use supports... One almost sits on the top muffler... Also, my other uncle doesn;t have any on his Harley, and his bags are always empty and they just flap around, it's funny...
