I have an '07 BMW R1200RT, its my favorite bike ever, so its on the list.
I would like to have a Ducati Monster 1200S just because.
I liked the BMWF650GS well enough to buy it although I still don't haven't found a niche for it in my life. . .
I'd like a Honda Trail 90, just for the memories.
I've never ridden a Harley, so I'll put the Road Glide on for grins.
