New bike, rode it pretty much regularly for the break in period - a mix of everything.
Bone stock, no bags other than a camelback.
Before 600 miles service avg about 50mpg.
After 600 mile service I avg about 53-54 mpg consistently. The OBC rating seems to be about right on give or take a mile per gallon or less.
I'm happy with it.
Ride more, bark less
