Depends on your definition of dual sport.
Is it a great bike? Yes it is. Can it go on and off road? Yes it can. And with a little re-gearing (lower) and the right choice of tires, it is remarkably capable in the off road part of the equation, put in the right hands.
But... if you have never spent time in the dirt,
Or... your idea of "off road is single track through sections of deep mud, or craggy rock, maybe this is not the bike you'd be looking for.
It is a twin cylinder "ADV" bike that can handle some stuff you'd not want to put your street bike through regularly, but it is not a true "dual sport" in my definition. I have the DL650's bigger brother, and I am willing to drag my old '04 DL1000 thru some pretty crappy stuff, but I also have a lot of off-road (no plate, enduro and MX) bike experience, and I think that makes a difference in confidence levels when the going gets rough.
So, before I blabber on any further, tell us your experience, and where yo hope to take the thing. Because that really maks more difference than the bike itself.
PS - Jer - Get some different tires and air them down. There are some really good 50/50 tires on the market in the 'Strom size and they make a HUGE difference like you would not believe. I'm looking at the Shinko Big Blocks this winter mostly because their price is so much lower than the others, but there are a bunch of options and they will all make a big difference in the soft ground.
