3 kg is the recommendation on overall weight for this configuration. ...

It's not just the mounting, it's also the weight hanging out the back of the bike.

An anecdote: I worked for a couple of months as a motorcycle courier a very long time ago. The bike was a Suzuki GSX 250, i.e. fairly light, and the courier box was mounted on a rack behind the seat, i.e. behind the rear axle of the bike. One day I got called to take a delivery from a foundry to one of their customers. I was young and foolish and made the delivery, but probably should have refused it. The rack held up to it, but the steering was so light because of the weight on the back of the bike that it was definitely highly dangerous.

PS: the Hepco Becker racks are rated at 5 kg. for the rack. Panniers 10 kg each, as far as I remember. I have a 40 litre box for the rack, and have definitely had more than 5 kg in it, both on the 1000 GTR that I used to have, and on the Breva 750. Nothing has broken yet, but that issue with the weight at the back taking weight off the front wheel should be held in consideration.
