When it comes to custom motorcycle builders, there's crazy and there's really crazy. Falling into the latter category is one Mr. Clemens F. Leonhardt, who has just finished building what he refers to as "the world's biggest motorcycle." Excluding some other crazy creations, such as the Monster Bike, the guy's got a point. Unlike other two-wheeled behemoths, the Leonhardt Gunbus is actually ready to ride on normal roads and will soon go into series production. That's right... you'll actually be able to buy one of these. Next on the agenda is an equally massive sidecar, which somehow seems just right for this bike.

A quick glance at the pictures shows just how monumental that 410-cubic-inch, air-cooled, pushrod V-Twin really is. Of course, a monster of an engine must require an impressively large bike, and the Gunbus is certainly that, looking bit like a caricature of a bike with the fittingly attractive blonde model sitting on top. Whatever -- we want one.
