Me and my engineering buddies from work are always fascinated with random engineering projects and weird stuff like this: Ducati Elenore 868cc V8 Ducati Elenore V8 Update Pretty interesting stuff if your in to that kind of stuff... Google Translate
Thats the strangest cylinder config i have ever seen. I guess the motion of the outer pistons "break" the cycle in half and made it smooth?
Seen it before not sure how smooth it would run with those crude inlet pipes... Anyway heres a small ver of the same config... Hows this for a Monkey bike Dan!
