This is a simple but easy tutorial on where to get dirtbikes besides buying them online. If you want a free dirtbike they are ONLY in the desert and forest locations. Try near trevors home as a lot of them drive on the road and some how get away with it... Once you have one you can go customize it and put new decals on it and upgrade it which most people dont know about. They are fun and fast so have fun running over things.
