I was clipping along at 65-70mph this past Saturday in central Florida (high 80 degrees) 2-up and got 49.2mpg.

Hope this helps...

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!

 

I ride all types of roads at all types of speed. I consistently get 42 mpg. I have pipes, SERT, SE ac and dyno tune

 

Just took a trip to Memphis this weekend and averaged 45 - 48 mpg. I've got an 07 FLHP with a 103", WildPig slip-ons and the rest is stock.

 

07 Ultra ..... with Stage 1 A/C w/K&N filter, Supertrapps, Nightrider XIED's, RJS Origionals and get 45 MPG with two up.

I'm happy.

 

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.

 

Averaging 42 MPG mostly two up. Setup is in sig.

 

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.
2005 fltri with se air cleaner,rinehart true duals and harley download nets me 46 mpg
mixed riding or highway.

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...
