Kawasaki made some notorious motorcycles in the 1970s, most notably the H1 triple with its hellacious two-cycle power curve. This custom monster boast 48-cylinders, six crankshafts and six Jaguar E-type distributors. Yeah, it's kinda hairy.
The creation of motorcycling madman Simon Whitlock, who in the past has built a fuel injected, water cooled, supercharged and nitrous-fed version of the aforementioned killer H1. This creation is cobbled together from a series of engines pulled from Kawasaki S1/KH250's and boasts a total displacement of 4200 cubic centimeters, and is essentially six, inline-eight engines, each with its own crankshaft, all tied together with gears and running through a BMW transmission. The engine uses six Jaguar E-Type distributors to get the sparks flying and a 75 cc pony motor under the seat as a starter. Believe it or not, the bike is barely rideable, but we're betting a change of pants is required after every trip. [Ridelust, BigBikeRiders]
