Arrow Wanna see a really B I G bike?

Did you ever feel small standing by a V2K? Then try this one:



Gunbus410 by Leonhardt Manufacturing...



...with a very decorative lady (just to get a clue of the proportions of the monster)...



...err... lost orientation? (still looking nice)



Lots of more nice pics at the manufacturer's homepage.
