Givi speed limits?

Hey all, new guy here. Dig the sight, and I've learned quite a bit just lurking for the past couple weeks.

I just picked up a 2002 DL1000 that I plan on riding cross country this summer. It came with a Givi top case, no identification that I could see but it's pretty huge. I noticed a panel that opens up from the inside of the top of the lid that mentions a top speed of 75mph when the box is on.

So my question is has anybody ever had problems with higher speeds, either with stability or with the case blowing off?
Thanks in advance for any input.

I'm convinced having a top case contributed to a tank slapper that threw me off. It started on a straight stretch of I-80 at a real 109mph. Aerodynamics and weight distribution are both negatively affected.

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

I have not heard of any strom issues and the givi tourpacks causing stability issues nor the loss of any packs. It is something one should be aware of at speeds though, as it could cause stability issues depending on the load. I had heard of a few incidents on the Honda ST’s years ago, and most occur with a top case on, fully loaded, and at high speeds.
I have run 110 MPH with my Givi V45 (?) at short stints, and know it is not as surefooted as it is without it, so the warning inside should be heeded until your comfortable.

I can't imagine my top case coming off the bike at any speed, it's quite solidly mounted. However, I don't doubt greywolf's story one bit. I could definitely see the case catching enough air at high speed (100+ mph) and trying to 'lever' the front wheel off the ground, so to speak. Taking a lot of weight off the front wheel at speed is a good way to induce a tank slapper.

I don't think I've gone much more than 75-85 mph with my case on yet, and I'll be cautious about doing so in the future.

Lots of accessory luggage manufacturers declare maximum speeds due to the aerodynamic instability they introduce. Even BMW stated max 80mph with their own, reasonably aero bags on my K75S.

No problem with my topbox cruising at 90mph on I-10 on my last trip. Speed limit there is 80mph. Had some stints of over 100 earlier in the trip with no problems. Definitely handles better at speed without it though.

My personal experience:

Givi E55, 105 mph verified by GPS on a closed road.

Givi E55 and V35 sidecases, 95 mph verified by GPS on a closed road.

ps... use a steering damper to take care of cross winds and other "stuff" related to steering. Makes a big difference. I swear by Scotts.

2008 DL1000, Two Brothers, PCV, etc., etc.

Just be careful of cross winds! It does act as a sail at to high of speeds.

After my low side the other day, I decided to pull my top box just to see if the bike handled any different without it. The bike seems more planted to me now. Can't say that it contributed to my low side, but the bike doesn't have the handlebar shake now that it had before removal. I think I will leave it in the shed for the time being.

When I am not commuting to work with laptop in my monkey-trunk.... I pop it off and leave it at home when I take my daytrips.

I do 'sense' a bit less stability with the monkey-trunk in place. But I remain cognizant of its presence and ride accordingly.

I believe my tall GIVI windshield also contributes to high-speed instability.

I have to also mention that adding the fork-brace really seemed to "tighten up" the front-end. It is nearly impervious to cross-winds now.
