There's an interesting story behind that rig.

When placing the radiator and its fan in the frame was found impractical, it was installed in the right rear half of the fuel tank with its intake in the location of the right kneepad. To prevent blockage of air flow by the right knee, the right footpeg was lowered. The air passing through the radiator is distributed by a duct exiting through the bottom of the tank. Excess air flow travels horizontally rearward then upward into that dome-shaped, tritium-powered, titanium heat exchanger just above the coil pack behind the kick starter. It is flushed through a Febreze-imbedded filter to enhance its quality as it passes into the atmosphere.

There wasn't sufficient room for the Jetronic under the seat so it was place in the left rear of the tank with a partition to separate it from the radiator and its ductwork. It's right behind what looks like the left knee pad but is actually the Jetronic's plug connector. The ignition control unit is in there too. Removing the Jetronic plug allows both units to be removed after their mounting latches are opened. The remaining forward section of the tank holds fuel. There's a fuel-tight baffle and insulation separating it from the radiator, ignition control and Jetronic.

With the alterations to the tank, many naysayers proclaimed that the resulting tank fuel capacity—750 ml—is too small. The fabricator answered by telling them to go build their own rigs if they're so smart.

The only real drawback in the modifications is that if the kickstarter is operated too vigorously, it will snap when it hits the footpeg. Reports of broken ankles during this procedure are anecdotal only, and unsubstantiated.

Minor defects aside, this bike is not only being touted as brilliant reengineering but also being hailed as an example of how to lessen moto carbon footprints by using inconvenience.

Of course it's real. Didn't you see the picture?

You are too clever! How about a pic of a Ural sidecar rig with a K75 motor?

Hey -- you're a real mechanic -- you don't need Photoshop for that, just an extra Ural, and extra engine, unlimited beer and shitloads of extra time.

Believe me, I'm looking for that Ural, already got a couple donor K75's lined up, got the beer & obviously, way too much time on my hands. Just need some eye candy for my shop wall!

Hard to tell with the low res file, but that could be a Ural 650 or Dnepr motor

That's be a bitch to Photoshop -- you'd need the camera angle from straight-on left and then you wouldn't even see the hack -- plus it's easy to Photoshop a 2 inch computer image but getting one with high enough resolution to print out for a wall photo -- probably easier just to swap out the engine.

But if you can get two good high resolution shots of the Ural and the brick engine from the same camera position and angle...doable enough.
