I've had some instances where dirtbikes come with "dealership titles."
Like people said already, a dirtbike shouldn't come with a true title that can be registered and tagged.
A good example would be a Bultaco Matador vs. a Bultaco Pursang. The matador came equipped with headlight and tail light, so it got a street legal title. The Pursang was Bultaco's true "dirtbike," so you don't really see titles for them.
