Mine is a 650 and I've had it on some long days of off pavement stuff. Rider skill aside, I found that it handles quite well considering how top heavy it is. Like Ash also pointed out, it has a lot to do with your choice in tires and for me, the handlebars were swapped out for ATV bars with a higher sweep which makes it easier to manage when standing on the pegs. Awesome bikes they are - congrats on the purchase. My favourite tires for off pavement on this bike are the TKC80's, but I have yet to try out the Heidenau's.
