Isn't that IT a big huge 2 stroke bike? Yamaha had a YZ490 as well that was a scary bike. I wish I had some pictures available but you can very easily convert a decent factory dual sport bike into a mean off-road machine. Weight can be removed or moved and there are street legal knobbies that are very aggressive. I even chose to use the DOT legal knobbies on my last off-road only bike since they were so dang effective and tough. (Tires are the Dunlop D606 series) So to the extreme there are street bikes like crotch rockets and then there are off-road race bikes like say a two stroke kick only no lights bike. There is a huge middle ground and lots of overlap for most riders. I desert race my dual sport and will be doing the annual 100 mile desert100 in two weeks. I fly by many high dollar dedicated off-road bikes with my street legal dual sport. It's not the bike, it's the rider. I have been spanked by crazy 50-60 year olds too. Those old guys are nuts, lots of broken bones in their history.
