Just remember that the street tires have almost no grip on dirt or gravel. I have yet to take my ninja off road, but I fly through my back yard every time I come home. I always turn into the gravel driveway, stand on the pegs and whack the throttle open in first, I spin the tire all the way up the driveway narrowly missing my car. Then I stop and open the gate to the back yard, and get back on, pick up some speed and then stab the rear brake to get the bike sideways, and slide up next to the back porch. Then I have to go cover up the giant groove of missing gravel in the driveway.
I've probably had more close calls in the driveway than on the street.
I want a dual sport.
