High 30's to 40 @ a steady cruise. F6B is a blast to ride but I'm sure that the CTX will be lighter & maybe easier to handle. Good luck.What are owners realizing in MPG'S I know Honda says 32, I remember my 1500's and 1800 getting about 40. I'm on the fence between the F6B and the CTX1300 where reports of 45+- have been noted.
Aggressive riding = 35mpg
Cruising = 40+ mpg
I also test rode both bikes and that settled it pretty quick for me.
