Great report - looks like an awesome trip.
I had a go on an F800GS a few weeks ago - Maffra down to Bellbird and back via McKillops Bridge with a friend who needed to get the hang of gravel riding. Lovely bike, probably much more suited to my needs than the 990, but it doesn't have the 'stupid grin factor!' http://d26ya5yqg8yyvs.cloudfront.net/icon10.gif
Hope the injuries are healing up - is the arm temporarily out of action or is it more serious?
