Question mileage with square vs rounded luggage

I did some searching but didn't find any threads, anyone compare gas mileage with squared off side bags like Trax vs rounded cases like Givi?

R.I.P. (Retire In Peace, thanks for the great ride.)

Gas mileage has more to do with your right grip than anything else, and it's much worse at highway speeds with any luggage sticking out there. The further it sticks out, the worse it will be. Some of the bags out there make the bike 4 feet wide.

I had thought the somewhat rounded profile of the Givis would help, and I figured the wind would flow past my legs and right over the bags. I was wrong. On a recent drone on the interstate with the E45s on, I stuck my hand down just in front of one of the bags. The force of the wind on my hand was considerable. Guess that's why Givi gives you a maximum speed along with the weight limit.

The rounded profile might slow down some of the turbulence, but I bet it's not a huge difference.

I agree with Tom, the faster you go, the worse yor milage will be regardless of what type of luggage

to many variables to do any real comparison, rounded bags may have a slightly better coefficient of drag, but every different size would have different frontal area

IMHO width of the luggage in more important than shape, as it adds to the frontal area

40" doesn't equal 4 feet but it does equal one huge ass.
40" is scary enough. My BMW is 34" I thought it was huge.

I can't even imagine 4 feet wide...that's just scary

Les
Mines 47 1/2 so pretty close to 48"
I really like the top loading aluminum panniers but it does make the bike pretty wide. It's not scary but you need to be aware when weaving through traffic, parking lots, getting fuel etc.





I haven't did any long term tests regarding fuel mileage but I would guess that I lose a few miles per tank with the bags on.

Hope this helps.

MPG

My Wee has the OEM bags, they stick out there, but the shape is is fairly good aerodynamicly speaking:rolleyes: When I added the 23in CeeBailey windscreen I noticed a drop in my MPG, but that has returned with further break-in miles. I have not checked the MPG without the bags, I carry stuff, that is why I have the bags in the first place. Dave

I notice a real decrease in acceleration above 55 MPH with my Caribou side cases - even when empty.
