Ducati V8 Project
Do you remember Dieter Hartmann-Wirthwein? He built that amazing little 125cc inline 4 Monkey bike. I guess Dieter isn't the kind of guy who sits around all satisfied with himself, he figured he could do something even better so he's busy working on another project, an 868cc Ducati V8, he calls it Ducati-Elenore.
This is still very much a work in progress, you can see from the photos the heads and valvetrain need quite a bit of work but the pistons seem to be situated in their respective cylinders so he's at least part way there. He's obviously a man of few words because there's very little information on his website. If my translation is correct, it will be a 2 valve desmo (No desmo, same as 125, Thanks, Hugo) with valves of 27mm and 23mm, the cylinders have a 56mm bore and 43mm stroke.
After everyone saw the patent drawing of the Ducati Elenore V8 built by Dieter Hartmann-Wirthwein, there was a lot of head scratching going on as everyone tried to visualize the engine internals in motion. I asked Dieter if he had any more images from other perspectives so he uploaded a few and, even better, the video he used at his display at Intermot. Seeing everything in motion answers a lot of questions and makes the design work look even more impressive.
Dieter also corrected one statement in the original article about the crankshaft, it's not the original, but is a new unit machined with a 44mm hub and offset laterally so the cylinder bank is centered in the frame. He sent the above photo to show us his work. He also said the crankshaft he used in the 125cc inline 4 monkey bike was the original.
UPDATE: As noted above, the 125cc Monkey bike uses the original crankshaft. Dieter confirms that the Monkey inline 4 uses the same piston and rod arrangement as the Ducati V8 project. If you're not sure it will work, watch the video below:
