I am 6'3" and 280 290. I usually ride just the coasters at KI. The Beast, The Racer, Mystic Timbers, & Amazon falls are tight fitting but doable. The Diamond back and The Bat i was fine in. The Banshee is iffy. i noticed the last time i rode the the Banshee i noticed that there is a sign for person of larger size should be in rows 4 and 5. I have rode Drop Tower once and i am too big for that ride. The Flight of Fear is also kind of tight. i never rode Firehawk. i do not ride The Racer that much
