Luggage racks were from Rally Raid, and were again excellent. They're formed with lots of slots and square holes in the steel plates so you can pop straps through to secure your soft luggage where's its best for that make of gear. I've seen them with Wolfman luggage, Walters Magadan bags and the Dirtbags and they seem to accomodate any gear equally well.
For luggage I used Dirtbagz as I've had them for years on DRZ400 and the old 625 and they hold enough for everything if you pack well, but haven't got enough space that you pack a load of extra crap. If you have extra space you'll find something to put in there as sure as there's shite in a donkey.
