My 05 R6 got around 40mpg, my 91 cbr got 55ish mpg, highway driving.
My integra gets around 30mpg on the highway. That's the best I've gotten since the engine build. I could lean it out a bit more at cruise, and probably be okay, but I'm fine with 300 miles/ fillup. Granted, I drive 600 miles per week on average. With premium gas prices, I pay about $60-70 per week on gas. I need a job closer to home.
Not if you aren't goosing it at every possible moment...
