I have an '05 SS1000DS and get no more than 45 mpg on the interstate. I get high 30's to low 40's around town. It's been disappointing 'cause I got over 50 mpg on the highway with both my '97 SS/SP and 998.I'm curious as to what kind of mileage you can get out of an SS. I just did a freeway trip of 146 miles from Colorado Springs to Denver and back and got a no kidding 60.8 mpg out of my 05 SS1000. Does anyone else get anything like that?
