Who invented the desmodromic valves?

(It should be noted that exhaust noise levels can exceed 110dB on full race trim.) The Desmodromic valve system was designed and developed by Dr. Fabio Taglioni. Taglioni was the father of the modern desmodromic valve actuation system, and worked for Ducati for most of his career.

Do all Ducatis have desmo?

The system kept the valves under control at high revs, Ducati won a bunch of races, and today, all Ducati’s use desmodromic timing, from the Scrambler lineup on up to Ducati’s MotoGP bikes. Ducati and desmo may be synonymous, but Ducati didn’t invent the technology.

Does Ducati still use desmo?

We’re seeing the storied Italian brand venture further and further out from its traditional comfort zone and that’s very exciting.

What is a desmodromic engine?

A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. An engine using desmodromic valves has two cams and two actuators, each for positive opening and closing without a return spring.

How much does a Ducati Desmosedici cost?

And it wasn’t cheap; new, the Desmosedici cost $72,500.

What is desmodromic valve actuation?

What is a Desmo engine?

Desmo is short for desmodromic, and it refers to the way that a poppet valve inside of an engine is controlled. In almost every four-stroke piston engine, the valves are opened via a camshaft and closed by spring pressure which comes from a valve spring. It’s a well-known system, it works, and it’s pretty simple.

How many Ducati Desmosedici RR were made?

1500
The Ducati Desmosedici RR is a fairly rare bike. Ducati made only 1500 from 2007-2009; of these, the US received 300. And it wasn’t cheap; new, the Desmosedici cost $72,500. However, these bikes do occasionally pop up for sale.

What is the history of desmodromic valve actuation?

Design and history. 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 the Ducati 125 Desmo.

What racing cars have desmodromic valves?

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 the Ducati 125 Desmo.

The word “desmodromic” is derived from two Greek roots, desmos (controlled, linked, captive) and dromos (course, track, in the shape of a racecourse ). It refers to the exclusive valve control system used in Ducati engines: both valve movements (opening and closing) are “operated”.

When did the Ducati Desmodromic engine come out?

Desmodromic valve actuation has been applied to top-of-the-range production Ducati motorcycles since 1968, with the introduction of the “widecase” Mark 3 single cylinders. In 1959, the Maserati brothers introduced one of their final designs: a desmodromic four-cylinder, 2000cc engine for their last O.S.C.A.
