Just... wow.
*weeping noises*

I don't have much of a hard on for vehicles, I admit. I will notice pretty cars and such, but I don't have any real lust to own one unless it was made before the year 1930. However, it seems Kaneda's bike from Akira is one of my rare exceptions, because the idea of owning a replica of this bike makes me pretty much want to flip out on the spot. With total joy.
Bandai and Medicom put their heads together for this one, which is a 1/6th reproduction that actually lights up behind the wheel (see the gallery so you can fap yourself raw to that gorgeous image). However, it will set you back 31,920 yen. It's worth every penny, in my mind.You can order it at Happinet already. Just be warned if I come to your house and see you own this thing, I will kill you for it. Just saying.
