I actually (ashamed to admit) went to the Honda/Yamaha dealership here to look seriously at/buy the nt700, when (thank God) I saw their used 06 FJR and the rest is history haha.
I also test drove an NT700, and wound up with a used FJR.
Have ridden solo literally 99.9 percent of the time, but was really glad that the pillion was available on the beautiful spring day my wife joined me for a ride.
Not "so fat", but "so big" at 6'5" that my middling fatness/fitness adds up to more than the NT 700 really wanted to haul.
I test drove most of the other ST's discussed here, and an '09 C14, and the FJR was hands down the best for me.
If only I could find a simple way to move the handlebars a bit further away...
