So . . . . there has been much conversation as to the mpg that the Tenere gets. Bagless, I have been averaging 46.1-47.0 mpg; 46 with a head wind. . . .47 with a tail wind. Now, that's what the bike say she's getting; doing the math at the pump, results in a 1.5-2mpg lower number. But, number(s) on that dash are a good indicator as to what's going on. Today, I put the OE boxes on so I could carry some vittles. Same road, speed(s), and head/tail winds. Exactly a 4mpg decrease. If you're a person that keeps the boxes on, you probably don't even think about them. Conversely, I hardly ever use them, so I don't think about them. So, when everybody starts talking mileage, and number start getting thrown around, there's bound to be some pretty drastic differences, all depending if you're bagged, or not bagged.

And, speaking of bags. . . . apparently big butts are preferred. I've been riding my bike to the gym for forever. Not one comment, positive or negative, about the bike. Today, with her enhanced posterior. . . . three people asked me about her. "is that a different bike" & "good looking bike". o_O Go figure.

Fuel mileage or fuel consumption is all about the speeds you travel at.
I can (could) get my Tenere to burn as high as 7.5 litres per 100 km, at speeds of 145 kph.
At a lower speed, perhaps at 100 kph, the burn is just under 5 litres per 100 km.
For the non converted, to metric that is.
It is a very biiiig difference in mpg.

Drag increases as the square root of the speed, and the power required to sustain the higher speeds increases as the cube of the speed, read exponentially higher.
Hopefully I explained this, however; other "egg heads" are most welcome to comment.

I totally agree. I've found that if I stay below 73mph (3,900 rpm is the key more than the speed) my fuel mileage is stays steady. 73 (4,000 rpm) and above, it starts dropping. So, I fully expect a mileage hit with higher speed, but today showed me how much the boxes specifically, impacted the mileage . . . . because all the other potential factors remained the same.

Yup more boxes = more drag = more gas at the same speed.
There's a sweet spot for a reasonable speed, to obtain a reasonable fuel burn.
Just don't expect to get the same fuel burn if y'all in a hurry.

Or put in layman's terms
