I Have an 07 turbo Sportster and I am getting 50 – 55 mpg on the road. WOW! I was just wondering what other riders were getting on the new fuel injected Sportster?

I have a '96 "non turbo"carburated sportster andI got 55 MPG riding 2 up yesterday.

 

I get anywhere from 3mpg to 9,125mpg.

Seriously, my mileage varies wildly, all depending on how I'm riding. My short commutes and well-enforced in-town speed limits ensure I get crappy mileage (37-42mpg). But once I get out on the open highway and stay there for a while, I can get 53-55mpg.

Oh, mine's an '08 1200C with 3K miles.
