Hahaha, I only get that if I don't give her a heads up before a big hand full of throttle. She starts the "WOO HOO's" when I hit 120kmh. On the Bandit 200kmh +. She asks how fast when we stop then grins from ear to ear. Off road's a different story. Stuck to me like paint. I don't notice the top case either and it's on there all the time.

rrrdbw I don't have Vario cases. I have BMW Pannier and top case. I ride with them all almost all the time, I am in California and find that it does not really interfere with splitting lanes, as long as you know that you cannot zip in and out of traffic. You have to remember that the rear is as wide as the front when you are coming back into a lane.

Sport Riding in the twisties, I have the pannier /top case loaded with gear/tool, supplies . I have not encountered wobbles or instability. That's averaging 80-90 on freeway. I have gone over 110mph with no issues at all. Concerning at times since the pannier/top case says do not max 88mph I think.

I keep them on in case I go somewhere I can bring regular shoes, store my helmet and jacket instead of dragging in with me.

I received a free BMW duffel bag , when I purchased bike when they had reflector issue and couldn't purchase panniers. So Dealership gave me bag for the trouble. I'm looking forward for opportunity to use them attached to passenger seat with fully loaded pannier on an adventure.

the glove I like your way of thinking Catbrown357 I would ride back in the 70's and load that bike up with stuff just need more bungee cords, and those bikes did not handle like a GS

Catbrown357 The suggested maximum load for the vario top case is 11 lbs. at a speed of 110 MPH. Now, any reasonable person could probably stuff 20 lbs. worth of stuff in the top case, which would reduce the speed to approximately 55 MPH. Most speed limits in this country range from 65-75 MPH on interstates. The point is, if you can feel 20 lbs. on the back of the VERY capable GS, you are way more sensitive than me. In fact, I would venture a guess that 20 lbs. of weight on the rear would actually help handling and braking by putting more downforce on the rear suspension and tire.

No Issues with stability

I have the same set up on my 2015 GS. Stability has not been an issue for the speeds we have observed both single and 2 up. (up to 180 kph) Cannot comment on anything faster.

I had a Ducati Monster before my GS and I had to ride with a backpack everyday. I was hoping I could get some opinions from guys who ride with cases on their bikes. Should I switch to the side cases for everyday use?
A loaded top-box makes the bike a bit more top heavy, but I've never noticed it actually affecting stability at high ow low speed. With appropriate instrumentation I'm sure you could find a measurable difference but, for me at least, it's definitely not enough to notice.

Niks I have all of the Vario panniers, depends on where I go, use top case or side panniers, rarely use all of them, but happens sometime.
Both side use for low center of gravity in long trips or in combination with dry bag above.
Only top case in short trips, for one night or so.

Even with aerodynamics of the brick I haven't issues about stability of the bike.

JMC I havee a top case only and it is stable. I do not like the look of side bags and side cases on any bikes.
Top case looks cool and it is fine on highway and off road as well.

Advart I don't have a Vario, I've got a two different top boxes depending on what I'm doing. Both are Givi Outback Trekkers which are steel (heavy) boxes. I have the smaller 42L and the huge 58L case that can hold two helmets. I've never had a stability problem with either case on any of my ADV bikes including my 2017 GSA... Having a top box is the my norm as well. I don't have side cases, but when I do, I use soft panniers, Mosko Motos... But 95% of the time it's a top box.

I also follow the guidelines as far as how much weight they can carry and how much weight the rear rack can hold. It's still heavier than I load the boxes....

I can see how overloading them can potentially upset the stability of the bike. That's why it's important to have your "preload" or "sag" set correctly. Actually it's important regardless if you have top case/box or not... Preload should always be set correctly for rider at the very least...
