Today, "Desmodromic" commonly refers to the typical valve control system of our motorcycles: it is currently used on all our manufactured Twin-cylinders and is an exclusive Ducati system. In practice, the opening stroke and closing stroke of exhaust and intake valves are controlled in this system, while normally, closure is
3 Feb 2017 Switching to Desmo heads took the side load and high wear off the valve stem and guides! and did NOT lengthen the already too long engine, that design got carried into the Pantah in 1978.

The Mercedes-Benz W196 Formula One racing car of 1954-1955, and the Mercedes-Benz 300SLR sports racing car of 1955 both had desmodromic valve actuation. In 1956, Fabio Taglioni, a Ducati engineer, developed a desmodromic valve system for the Ducati 125 Grand Prix, creating

Desmodromic valve gear
6 Dec 2012 This was an introductory guide I wrote a few years ago about adjusting 4V (specifically, Desmoquattro) valves on a Ducati. First, lets look at the desmoquattro setup. We have a double overhead cam design driven by automotive-style timing belts on the right hand side of the engine. There are two rocker

Ducatis are famous for the Desmo Valve System. This system was first used by Mercedes in the 1950s on the W196 Grand Prix and the 300 SLR. But what is.
