- New Desmosedici GP engine for production
- Key features include counter-rotating crankshaft
- Cutting-edge tech from racing to the road
BOLOGNA, Italy – Ducati has given a preview of a new four-cylinder Desmosedici V4 engine designed, the prestige bikemaker says, “to power the Ducati supersport models of tomorrow”.
Transferring the technology of its most cutting-edge engine from racetrack to road, Ducati added, would give customers access to performance honed by years of MotoGP experience.
“The Desmosedici Stradale,” Ducati says, “will become yet another history-making Ducati milestone – the first time the Bologna-based company has put a four-cylinder engine in a production motorcycle.”
The “first look” was in Misano during the San Marino and Rimini Riviera GP, Round 13 of the 2017 MotoGP championship – regarded as a natural setting for the presentation because MotoGP is the proving ground from which the new engine drew its technology.
Claudio Domenicali, Ducati’s CEO, told Carman’s Corner in a media communication: “It’s with undiluted pride that we unveil this technological gem, the start of a chapter which will underline our vitality and commitment to investinbg in new products.”
BIG TORQUE AND POWER
It also, he added, highlighted the close collaboration between Ducati Corse and the factory bike development team; a demonstration of how much racing can be involved in developing technology for production bikes.
The official introduction of the engine will be in the new Panigale V4 on the evening of November 5 2017 at the Misano Circuit in Rimini, Italy.
Some detail about the engine…
To maximise mid-range torque – “essential for a satisfying road experience”, Ducati says – and ensure punchy torque and power at lower revs it has a slightly larger displacement than its MotoGP counterpart (1103cc). Power output exceeds 155kW at 13 000rpm, torque exceeds 120Nm from 8750 to 12 250 rpm.
READY FOR 2019 RACE SEASON
An R version of less than a litre but capable of high engine revs and intended more for track use is “at an advanced development stage” to be the foundation for a version homologated for Superbike racing.
It will be available for the 2019 season.
The 90° V4 configuration, Ducati explains, has made the engine extremely compact to allow centralisation of mass and smoothing incorporation on the frame.
“The Desmosedici Stradale has,” Ducati told The Corner, “been inserted with the front cylinders banked 42° back from horizontal, the same as Ducati engines employed in MotoGP.
“This optimises weight distribution, allows larger radiators, and sends the swingarm pivot point forwards. Its architecture also balances first-order forces without the added weight and power loss that a balancing countershaft would involve.”
DUCATIS FASTEST IN MOTOGP
As in MotoGP, the engine has an 81mm cylinder bore, the maximum under MotoGP rules and the biggest in the four-cylinder supersport segment.
Of course, the engine has been designed around the Desmodromic system, a key characteristic that helps to make Ducati prototypes the fastest in MotoGP.
“On this high-revving engine,” Ducati says, “the Desmo system achieves a degree of sophistication, lightness and compactness never before seen on a Ducati.
Variable-height air-intake horns are another first for a Ducati factory bike, it’s claimed, to optimise cylinder intake across the rev range with a consequent significant advantage in power delivery and handling.
Completing the fuelling system are the oval throttle bodies, each equipped with two injectors – one above the butterfly and one below.
“This package of cutting-edge technical solutions – absolutely unique within the Supersport segment – makes the Desmosedici Stradale an engine like no other in a motorcycle.”
