If the Vs. 650 hit its midrange cam in the dirt, gravel, or grass, there would be a cloud of dirt and rocks flying and impossible to keep upright. The power delivery of the Vs. 650 would not be as robust as many single cylinder 650's (BMW, Husky, ...) The power is definitely there, but not in the right delivery format equating to maximum traction for the dirt, imo of course. But then again, most dual dirt bikes just poot around on gravel roads at the most. That's a drag in time and fun considering the potential of the Vs. 650 on the street. But if that is what makes you happy (or you live in the sticks), that is the important thing.
