I don't ride city, so it's hard for me to comment on that. But, I do ride rural country highways and backroads...and some interstates. I consistantly get between 48-50 mpg's using 6th gear @ 2000 rpm. So that comes out to 55-65 mph on 2 lanes, and 72-75 on 4 lanes. All I have is SE slip-ons. My best friend gets the same!
my 08 rk, was averaging 42mpg. all stock except for tommy gunz slip ons. now I'm averaging around 46mpg. thats riding two up 90% of the time. have around 9600 mi. on the rk. seemes to be getting better mpg as the engine gets broke in.
I have to admit I'm not that concerned with mpg on my bike.
however it is a good indicater of how well the bike tuned.

I get 37-40 mixed with about a 50/50 split of 2 lane country roads and city. I got 43.7 on the highway at 75ish. Haven't really gone on a trip that is exclusively 2 up so I can't tell you what that is...
