If the KLR owner in you is too strong to buy the AltRider ones, which are closed at the top, unlike the Touratech ones, then go get some aluminum sheet from Home Despot or Ace and make up your own. It wouldn't have to as fancy as the AltRider ones, but that concept of up and angle in, then over to bolt down or hook over another piece could be made with a few simple bends. A small bench vice and a rubber mallet, plus a hand drill and some aviation snips and you could do your own cheap. Spray them black and ride on.
