The DR is heavy for it's engine size, weighing more than most 450 4 strokes - including the dual sport ones. Plus its an air cooled tractor engine. Basically what I'm saying is its a poor example of what kind of power you can get from a 4 stroke. On the upside however, they last forever and get great gas mileage.
