Fuel use is more related to how much horsepower you're demanding from the engine vs. what rpm your running. A CB1100 running down the highway at 75 mph in sixth gear should get very close to the same mileage as one running down the highway at the same speed in fifth gear. The frictional loss of the engine running at higher rpm would be negligible.
I didn't vote on this poll because my mpg varies greatly depending on the kind of riding I do. In the city, with lot's of stops and starts with (usually unnecessarily) hard acceleration, I've turned in 40 mpg. While on a back road with no stops, averaging 55-60 mph I've gotten 59 mpg out of a tank. I suppose my "mpg" would be somewhere in between, but I'm not sure exactly where.
