Riding motorcycles are great for the speed and thrill, i prefer on the road, and not off-road though.
I perfer country roads in unpopulated areas where the speed limit is 80km/t (about 48mph), since you can take the turns pretty low, and still have hope of surviving whitout permanent damage if you whipe out. So far, i haven't had any accidents on my motorcycle, and i'd like to keep it that way :P
