Back flip a dirt bike?

hi im 16 years old and im thinking of attempting a back flip on my motorbike. i have a 2003 kx 250 2 stroke and ive been riding for a while now. i can to big jumps and i want to see if i call pull it off. i know it's extreamly dangerous but i dont know where a foam pit is in NSW australia. if i can pull it off is there a chance to be a freestyler and learn other moves. oh and any tip will be good. thanks
