I don't know if there's going to be a Batcycle in the new Superman vs Batman movie, but this bike could work perfectly without any modification. It's the new Ronin 47 from Ronin Motor Works, based on the Buell 1125. It's a strikingly beautiful and unique machine. Only 47 will be made.
Check out more footage from Carl Erik Rinsch's long-delayed feature which reworks the classic Japanese story of the 47 Ronin. Various adaptations of this story are common, however this could be translation with the most artistic liberties, as it's set in a fantasy world.
