Some technical low-down on the new Ducati MotoGP project

Ducati commences its greatest challenge in attacking the MotoGP World Championship this season. Here is a little bit of information about what will be happening underneath those blood red fairings in 2003.

Initially Ducati's MotoGP technicians considered creating a ´super-twin´, a new-generation v-twin prototype that would take advantage of technical regulations offering twin cylinder bikes a weight advantage over four-, five- and six-cylinder machines. But detailed studies, including numerous computer simulations, suggested that a twin would struggle to produce the immense amount of horsepower – around 220bhp – required, without excessive revs. They finally decided upon an all-new V4 engine, mimicking Ducati´s traditional L-configuration v-twin layout, and incorporating the desmodromic valve operation. The motor was tagged Desmosedici because it has 16 valves (sedici is Italian for 16) and the valves are operated by the desmo system.

The 90-degree ´L´ configuration provides intrinsic engine balance, a fundamental consideration in an engine that revs at over 16,000rpm, and minimum vibration, good for mechanical efficiency and reliability.$$$

The Desmosedici engine is looked after by a brand-new Magneti Marelli CPU engine management/fuel injection system, which combines maximum performance with optimum fuel consumption.

While other manufacturers race with variants of the ubiquitous aluminium beam chassis, the Desmosedici uses a tubular steel, trellis-type chassis. This concept allows excellent rigidity where required, as well as some flex, a useful factor in eliminating chassis ´chatter´, a particularly complex problem in modern racing. The Desmosedici continues Ducati´s association with Michelin and also with Ohlins.
