Stock, my '04 Road Glide would get 40 to 44 MPG at all times. At 5,000 miles, I added slip ons, a race tuner and stage 1 kit. I've noticed at 60 MPH, I'll still get around 40 MPG. At 70, it's more like 34-36 MPG. At 80 MPH, I'm getting around 32 MPG. I need a six speed.

 

All the mileages stated are pretty good...one thing is sure, I did not buy this bike because of fuel economy...it is purely for pleasure. The good mileage is just a bonus.

 

Too many pages to read through now, this should have been posted as a survey!

 

I get the same most of the time 42-45 mpg day to day driving,now when Im on all day it can be as high as 50 if I keep the engine under 3200 RPM and that is about
73 mph
thats on a 05 Roadglide 95,SERT T-header

 

my 09 SG is averaging around 38 with my short commute to work...a little less if im riding hard...worst been 35. On my ride to and from the smokies from MO, we traveled 2 lane blacktop averaging 60 and under and the bike got 50-52 on several tanks. Bike is totally stock and now has a little over 3000 miles. My mileages are very similar to what my 2000 RK delivered.

 

07 FLHP, bone stock 103 w/ stock intake and exhaust. 70 mile commute daily running at 80mph, getting 32.6 mpg. we'll see what happens when i do the air cleaner, fi controller, and exhaust.

 

I traded in my '04 Ultra for a '09. My '04 had a Stage 1 kit, Samson Silver Bullet mufflers, K & N air filter, and synthetic oil, it got between 45-52 mpg solo or two up. I know have 2200 miles on my '09 and the best mileage I got was 42 mpg. I haven't done any performance upgrades on it yet. The '09 Ultra is a great bike with the exception of fuel economy, smooth and easy to handle.

 

Damn...I must be doing something wrong. I have an 08 Ultra, with a PCIII, monster ovals and a AN Big Sucker. I have about 1500miles on it so far....I average around 35mpg and my last 2 tanks were only 33mph. I do ALL freeway driving...mostly in 6th gear. I had a V-Rod that got better gas mileage than my Ultra....hope the mileage gets better with more break-in.

 

Just checked last friday. Got 38 mpg.

 

My 08 got pretty sucky mileage for the first 1000 miles or so - but after that settled in the low 40's - of course I don't baby her - the wife loves that rumble off the line! ;-)
