I measured 2 tankfulls, 1st run at 80-90mph(72-81 true speed) and being aggressive on the highway with a light headwind of less than 5mph, I got 47MPG. The 2nd run at 70-75mph (63-67 true speed) light on the throttle but with some light passing with a tailwind of 15mph, I got 64MPG. So it seems I got some pretty good mpg at a lower speed but with a good tailwind. Are those getting upwards of 60mpg consistently running at 60-65mph(54-58 true speed) without figuring the 10% error? It just seems awfully slow for highway speeds. Thanks!
My mileage is in my sig... You can click on it for more details, but basically that's just an average over tankfuls... Each time I fill up, I record the mileage and amount I put in it. I almost never ride highway only, or city only. But my average is right around 60. However, I once reached really high mileage when I was commuting an hour to work, and specifically remember the wind being behind me both directions to work and from work 8 hours later... and I wasn't in any hurry at all.
I will add that a lot of the roads (nearly all, in fact) I ride on are 55 posted speed limit, and I'll ride at 60-65 indicated... Most of these roads are about 5 miles to get to through the city first... so maybe there is some truth to your conclusion there :dunno_black:
I probably need to update with about 3 or 4 more tankfulls on that sig calculation, as I imagine it has dropped below 60 since I added my R6 throttle tube.

One tank is not a good measure of MPG. There are variables when filling the tank due to the air space and the filler neck. Sometimes I get a single really high or low reading. It has to be averaged to really know your mileage.
The speedometer is off 10% but the odometer is correct.
