I have gotten as high as 52-53 on several tanks of high altitude low speed cruising and anywhere from 36 high speed interstate to 48 moderate speeds Average in the low-mid 40's. Rinehart slip ons big sucker and stage 1 tune, almost always two up.

 

A lot better then my truck!!

 

Over the last 7,157 miles my average is 43.44 mpg.

38-40 city, 46-48 highway

 

41-43mpg seems about normal for me 09 Road King bone stock, no highways here just a lot of putting around. I think the first 1k miles a got a little less than what I get now. My lowest I think has been 37 mpg and highest 45 mpg.

 

I get 45-55 depending on what I'm doing.

 

36 - 40 mph - 00 Electra Glide Classic, true duals, PCIII, A/C kit and SS510G cams. Highway between 70 -75.

 

35 city / 38-40 highway

 

i average around 48 on my tc88 with minimal performace parts (stage 1). also i ride like im trying to keep this bike awhile, not trying to destroy it. Your aftermarket parts will effect your horsepower which will directly effect your milage.

 

'09 EGC solo highway at speed limit = 47 mpg

 

Average of 38-40 kills my stock '02 Ultra Time in and time out.
