Driving style does have a lot to do with it.
I ride a Honda Magna. I average around 45 mpg.

When I ride lightly, I can get over 50-52 mpg, with a one-time peak of 56.

My friends don't know how--they get 30-35 mpg. Well, when I ride with them, so do I. Lots of high revs, racing and braking (it's a crotch rocket engine in a cruiser frame). To me, that wastes gas and wears out the brakes. I'm lucky if I hit half the max redline (10k RPM).

As Randii loves to say, "Your mileage may vary" (YMMV)
