Well,of course it's a good reproduction of the bike,but the one i'm asking for help is a REAL KANEDA'S MOTORBIKE
Oh that, it's just a promotional model that's been at variuos shows in Japan.
If there were any plans to make a real working replica of the bike it would be everywhere on the internet.
I'd stick with the 1/12 if I were you.
HLJ's pics of the Koenig are great, thank heavens they didn't miss it.

Also mentions the NEO-FUKUOKO(bike in the cons) project as an "allegedly functional motorcycle".
