Ask any Ducati owner (or dreamer) 'Why?' and they will invariably say that it's all about the DESMO.
The appeal of desmodromic valve actuation during this time mainly came from the propensity of valve springs to snap or float at higher rpms which often lead to catastrophic engine failure.
Desmodromic valves get around these problems by using a second set of rocker arms and cam lobes to shut the valves directly. This means that regardless of engine rpm, the opportunity for valve float is eliminated.
Float or no float, it's the magic of the abstract design on the softest t-shirt on the planet that makes the Desmo such a match for the abstractRPM line up
