I'm getting a Nomadic Rack off of KTMtwins and will use a Giant Loop Coyote bag for storage.
How much weight can / have people run on the tail rack - for extended rough country duty? I won't have a rack supporting saddle bags and the rear rack up from the frame.
I'd like to use the back rack for a Kolpin / Rotopax 1.5 gallon can stacked horizontally with a light sleeping bag on top of it.
Ideas.

Thats a problem area for the 690 & you should research carefully before you mount a bunch of gear back there. Any weight you put on a rack behind the seat is 100% supported by the plastic gas tank. I think they say 15 pounds is max but even thats a lot of stress on the tank when off roading.. I've heard plenty off cases where the bolt threads have been ripped out of the tank where the rack bolts on. Even broken tanks from too much weight & those are $$$$!!!. A Rotopax hangin off over your brake light wont last long on a rough trail. Move it as far forward as you can. When I travel I carry a duffle strapped on my rack but balance some of the weight on the seat also. Hope this helps, good luck!

You should be fine with the 1.5 gal of gas and the light sleeping bag. A gallon of gas weighs just over 6 lbs, not including the container. But I do second what Rockeboy says. I have the Nomadic rack and its quite bomber. The weak link would be the threaded inserts in the tank. I haven't read where people have been ripping out the threads or the inserts, but I have read complaints about other rack designs breaking due to the rack not being stiff enough and flexing 'till breakage. That being said, I haven't had much more than 15 lbs on my rack and traveled off road with it loaded, just paved roads. You should contact Nomadic Racks to see if they know of any issues with their rack and the 690 Enduro.
Hope this helps.

Here is a quote from Rusty Shovel on his Nomadic rack. The side racks may also add support against flexing because they tie into the foot peg brackets.

The rear rack has remained solid. I've taken the entire setup camping with a pair of fully loaded Wolfman Expedition bags, 2 gallon Rotopax, and my trusty walmart lunchbox on the tail rack (probably about 50 lbs) with no issues.
I take that back, I have had one issue. I went to Big Bend with a fully fueled Rotopax and after a couple of days of hard riding I noticed that two of the bracket mounts for the Rotopax holder had broken. I'm gonna call Rotopax and see if they'll send me some beefier brackets.
The racks have all been solid. If fact, the Touratech rack has been forced into roll cage duty and has done well.
I'll get some photos of the broken brackets up soon.

If you are going to add very much to the rear rack read this Tank subframe bolts at
http://690enduro.createaforum.com/general-maintenance/tank-subframe-bolts/ (http://690enduro.createaforum.com/general-maintenance/tank-subframe-bolts/)
The best solution is Perun's kit from Serbia.

Thanks for all the input on the rear rack capacity.
I have ordered Perun's kits for our bikes and I bought safari tanks - I liked the idea of packing fuel with the safari versus kilpin bottles.
-
I bought a kit from Perun. Good quality. Kinda a bastard to install by yourself. Two sets of hands recommended.... that or don't drink while you install it, like I did.

I second replacing your upper and lower tank mount bolts. Easy to do and the aftermarket has much stronger solutions.

I wanted to chime in to be clear that, when paired with Touratech side racks, most of the weight on the rear rack is supported by the passenger foot peg brackets, so the tank threads don't handle much of the the load. That said, I've never read any complaints that the *plastic* (usually said with a sneer) actually failed; only the subframe bolts, which can be replaced with beefier versions mentioned in this thread.
I don't think the tank *ever* fails. I think it's actually made of adamantium.
I've never heard of the metal threads failing, which mean it will probably soon just so the universe can show me how little I know (again).
Also, my apologies to Rotopax, it wasn't their mount that broke. It was the Wolfman Pawnee Plate's brackets that snapped. Wolfman said it's sending me beefier brackets soon.

So I've been rocking the perun kit/ nomadic rack for over a year now. I roll with 30 lbs on it easily. If it's gonna break, so be it. Then I'll go to a frontside gas tank again. Yeah, having that damn fuel tank where it is seems to be a huge ergonomic downside, but it's part of what makes a 690. We just keep adding all sorts of **** to it and expect it to do it's damn job. Well, there's a breaking point for everything. Just get the upgraded bolt kit. :P

Hey guys-Noobie on this site but but running one of the 1.75gal Rotopax on a SWMotech rack and the weight broke the rack.
It took almost two years, but it broke.
I don't put anything larger than the 1 gal Rotopax on the back of the bike now.
Riding a 2012 if anybody's wondering.
