If you use "throw-over" saddlebags, that is - bags that are connected to each other and just hang from the seat, then all a soft luggage rack has to do is keep the bags from getting toward the rear wheel or contacting the swing arm on deep compression. I have made simple racks for a dozen bikes at this point. They all work great and are quite universal, accommodating moto, bicycle and horse panniers. The ones on dirt bikes have hit hard plenty of times and just keep going. The one on my RE-Strom may have hit the ground a couple of times, but, as I was the only witness, you can't prove it. If you've got some basic metal fab skills, you might find it a pretty good way to go. Just got back from a week long ride around BC with my brand new, minimalist DR650 creation and they worked great with an old pair of bicycle panniers.
