Give the Z-T a try. I'm 5'9" w/a 30" inseam and the BMW low seat. If you're a little differently set up, it might be just the ticket. The Z-T and winglets were a huge improvement over stock, just a little rougher than I would have preferred. Although the calmness behind the Givi is nice in the 40 degree weather now. It makes me wonder if I'll get enough wind in the summer. I guess there's no pleasing some people... Maybe I'll hold onto the Z-T, just in case!
