What do these two bikes have in common? Well the were built by Dieter Hartmann-Wirthwein. I don't know much about him other than he had a motorcycle accident in 2002 which left him paralyzed from the waist down, but that hasn't stopped him producing these engine conversions. The four cylinder Monkey Bike took about a year to build, starting early 07. If you click on the title it'll take you to the web site, then go to videos and listen to the small 125/4 engine, sounds great, nearly as good as a big Kawa... As far as I know the V8 Ducati is nearly finished, should sound nice.
Pic below shows the layout of the V8, there is a video of how it works on their web site.
Pretty amazing stuff. Reminds me of a pic I saw in a Popular Mechanics megazine years ago, of a miniature Porsche 6 cylinder engine that you could hold in one hand, that actualy ran.Some really talented engineers out there. Hairy Larry
