I average right at 50, 47 to 53 depending on how I drive. TC 88 with stage 1 and Python pipes.

 

my 883 would regularly get around 55. softail would only get in the 30's.
the vic is averaging about 45

 

My 07 Heritage does around 40 to 45 on most trips. But coming back from Vegas to Palm Springs it was over 52. Good tail wind didn't hurt.

 

50 mpg on the highway and 32-35 in the city.

 

My stock (not for long) RGU got 42.6 mpg on my last fill up. Thats with mostly 2 up riding....

 

I'll be damned, maybe I really did get 50. Cool. I didn't figure this softail would do that.

 

My worst was around 40 because I was riding hard that day.
My best was 54 because I was riding like an old woman.

 

I get 50-52 on my 07 Ultra, one of my buddies, who has a 98 Ultra with a 88, gets 57 mph....now I also can get less than 30, when playing.

 

My 06 FLSTN gets 45 mi./gal. This is on the back roads of NEPA.

I had a Honda XL 250 back in the 70's she would get about 80 mi/gal.

 

I got a 2000 bagger that i recently put new plugs and wires on, I 'm getting about 45-50. Seems amazing, but the numbers back it up.
