Better to run my tailbox or my panniers?

Most of us have seen that hard luggage can significantly impact mileage. I have a Givi V46 tailbox and E21 panniers. Most of my rides are day rides and I only need one, not both. I'm wondering which penalizes my fuel economy the most. The E21 panniers get a lot of bugs on the front and the tail box gets none so I am assuming the tail box is catching less wind and thus is causing less aerodynamic drag. Is this correct?

Also, I assume there is a handling penalty with the tailbox vs panniers because the weight is higher up. Correct?

Fuel mileage? On a 650? Even if one or the other cost 5 mpg that's less than a penny a mile. Just ride with whichever you want.

What SCraig said You may want to consider the extra protection paniers give in a fall. Just sayin. You should not have enough weight in the tail box to make any diff. Riding with a passenger hardly affects my 650.

ADVENTURE, like beauty, is in the eye of the beholder.

A top box is the worst place to add much weight. It is farther away from the center of mass than any alternative. Tank panniers, a tank bag and low and forward in the side cases are better for weight distribution.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

As he said

Top box gives a higher centre of gravity when loaded and you may also feel air blowing against your back due to the vortex effect created between your body and the box [this can also create drag which is why trucks have roof spoilers to deflect air upwards to eliminate or reduce the vortex].

Panniers may be wider if lane filtering at traffic lights [but I think the E21's are no wider than the handlebars], also they won't hold your helmet[s] while you are away from the bike.

I put my stuff in a backpack then in my V46 top box for day rides, that way if I need to pick stuff up during the ride or on the way home I can put the pack on my back and fill up the top box for extra capacity if needed.

Personally I don't notice the change in the centre of gravity with the top box loaded but then I don't ride at ten/tenths that often.

Also my Wee fully loaded with top box-panniers and tent/camping gear bag still only weighs in around the same as my previous BMW R1150GS did unladen.

Actually there seems to be very little difference in the handling characteristics whether laden or unladen.
Acceleration and braking are the most noticable differences I have found, the same applies running two up.

I'm not worried about the cost I'm worried about the range. One of the reasons I bought the wee was the range, here in the mountains of California it's not hard to go 200 miles between fillups. Hard bags often cut much more than 5 MPG...if you look at the big aluminum panniers, they can cut your mileage by a good 25%.

E21 sidecases totally....best place for mass....low and split side to side. I try to locate as much mass as I can, as low as I can. I've even gone to the extent to wrap and zip-tie my tire levers to the subframe.

While I do have an E52 topcase, IF it gets used, I ride with it empty and use it to stow my riding gear when I arrive. Too much weight up there makes for an unsettling ride.

I agree that the fuel hit can be pretty heavy, but the biggest problem with poor mileage has to do with your right wrist.

I dunno, maybe its cause I have fat thighs that deflect the wind first, or maybe the Vee doesn't take the milage hit that the Wee does

I haven't seen any difference in fuel economy with my side cases on or off, nor have I seen bugs on them

The Givi E360's I run on my VFR cut mileage exactly zero the best I can tell. I've never noticed any difference whatsoever with them on or off (unless they are loaded to the stretching point). I've also never noticed any difference on my V-Strom with a tail bag and/or side bags or a DL1000 with tail bag and/or side bags. If those aluminum cans are cutting 25% off the fuel mileage then someone is loading them with concrete blocks.

My advice, if you are that concerned about distances, is to carry a gallon of gas in one of them.
