The image of vehicular swagger above really speaks for itself. It's Kaneda's bike... in real life! Before we get to the Why's and How's, though, let's put this hog into some perspective.
Back during one of the aborted live-action AKIRA's many, many leaks, a wave of gasps arose after Chris Weston, a conceptual designer (and superb comics artist,) dared to suggest that this signature red motorcycle needed a redesign to look more believable on screen. Scandalized fans responded, as is their wont, posting pics of numerous past attempts at recreating the machine.
A few looked rad. Most... looked absolutely goofy.
What sets this effort apart is that it’s the first officially approved one. As relayed by Kotaku, the owner sunk seven years and a cool $121 K into it, then made a country-wide trek on it to raise money for autistic children. For the finale, he parked the thing permanently in a new museum exhibit dedicated to Otomo.
As you’ll see in the vids below, the bike certainly works (even though one must still wonder how its design affects basic issues of turning and acceleration.) For my money, it maybe looks a wee too clean and shiny for something that’d be in the possession of a rough 'n tumble, rumble-prone gang leader. But hey - - this wouldn't be the first time form's won over function in anime, right?
Given the timing, you've also got to wonder what creations Otomo’s forthcoming historical manga might inspire. Might we someday see precise recreations of the leads' Meiji Era horse carriages?
