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.
Each bike will be named after one of the samurais in 47 Ronins, with a price tag of $38,000 per unit. I'm sure they won't last long. Only 12 have been made so far and five have already been sold.
Thanks for the tip, Sergio!
