This 360-degree crankshaft (left) and camshaft (right) with identically timed lobes are from the original Twin Pulse Desmosedici, which had the two cylinders in each bank firing together. According to Filippo Preziosi, Ducati Corse's technical director, "The layout used from 2004 onwards was on the other hand similar to a twin but not entirely. In other words, combustion of the four cylinders was very close to 'two-by-two,' but not exactly at the same time as in 2002."
