Your definitely going to want to trailer, van or truck whichever bike you are going to ride at the track. In case of a wreck or other mishap, also.. most tracks require you to cover your headlights, remove your mirrors, turn signals etc which makes riding to the track a little difficult. Im not sure what tracks your close to but try to find their websites and research what their requirements are. Go to
