If you’ve come across the complex patent drawing of Dieter Hartmann-Wirthwein’s Ducati Elenore V8, chances are high that you’d be quite stupefied. Thanks to Paul Crowe at The Kneeslider, Dieter posted a few images and even some videos explaining how everything works. At the time, Dieter was looking at around 80 horsepower from the compact V8. Best to watch the video before this turns into an engineering lecture!

Dieter also says his Monkey inline-4 uses the same piston and rod arrangement as the Ducati V8 project. The clip below shows that it ‘works’.
