(aka) Warriors of the Year 2072 / Rome 2033: The Fighter Centurions / I guerrieri dell'anno 2072 .

In the future, two television networks compete for ratings by producing violent game shows. One network produces a modern day version of the Roman gladiators, only on motorcycles instead of chariots, and uses convicted murderers as the participants, The network decides it needs a champion for this sport, so they frame a constant winner from another game for murder, and place him on the show.
