Ducati will now be powered by the 210 bhp Desmosedici Stradale V4 engine.
A new chapter in Ducati’s rich lineage of engines and the 1103cc plant screams at the top of its voice at 14000 rpm.
In what will go down as the biggest shift for the company, Ducati officially launched its four cylinder V4 Desmosedici Stradale engine at the Misano World Circuit on Thursday, 7th September 2017.
It will be replacing the Superquadro twin-cylinder which is having its final run on the mighty 1299 Panigale R Final Edition. The first motorcycle it will run on will be the Ducati Panigale V4 to be unveiled November 5, 2017.
Ducati’s already runs a 90-degree V-four cylinder plant with desmodromic valves on their MotoGP bike and is called as Desmosedici.The same name is now carried on to their new engine that will fit onto the street version’s frame. And ’Stradale’ simply means ’road’ in Italian.
As a company first, the Italian brand will equip their bikes with a four cylinder engine, with the first one to be launched in November. It will be called as the Panigale V4 which we saw testing on the streets with full test equipment and light camouflaging.
The engine has been developed along with the folks that run the show at MotoGP. The engineers have made sure that this machine will allow the rider to hoon it on the track with all of its 210 hp belting out at 13000 rpm.
The four pot motor is also road-friendly with it having a larger displacement than the MotoGP counterpart, 1103cc to be exact. This gives in for a healthy mid-range torque and a punchy low-end torque at just 8750 rpm. Maximum torque of 120 Nm comes at 12500 rpm.
The engineers have tuned this to have a ’twin-pulse’ firing sequence which will give this Desmosedici Stradale its unique exhaust note; thanks to the 70° offset of the crank pins. Sounding similar to Aprilia’s RSV4, this V4 from Ducati will also make use of the “big bang” effect for maximum traction while exiting a corner.
The 90° V4 engine will also borrow cues from the Superquadro v-twin engine design elements to get the right packaging and balance, allowing centralisation of mass and minimal vibration of the motorcycle.
Just like on the MotoGP machines, the front cylinders are banked at a 42° back from the horizontal which allows the chaps to fix in a much larger and efficient radiator that for optimum cooling.
It will not only be seen on just one model but an entire lineup of high-powered motorcycles Ducati plans to unleash onto the world streets. With this, the company wants to reconquer their World Superbike dreams along with the recent success in their MotoGP stint.
To do that, the company has designed this engine with an 81 mm cylinder bore which is the maximum allowed by MotoGP rules and will become the highest in the four cylinder machines running in any of the competition. This facilitates the same fluid dynamics architecture as used on the Desmosedici GP engine.
Overall, this is the brand’s most technologically sophisticated and compact power-plant ever created that is believed to annihilate anything in the litre class superbike segment. And calling it as Desmosedici Stradale, you know how serious these guys are.

Ducati is also undertaking advanced development of an ’R’ version of this engine that will have a displacement less than 1000 cc but will rev higher than 14000 rpm and produce more power. It will provide the company’s Superbike championship dreams with a key for them to open entirely new possibilities.

Desmosedici Stradale: a V4 for the Ducati sport bikes of tomorrow
New engine directly derived from the Desmosedici GP soon to go into production
Key features include Desmodromic timing, counter-rotating crankshaft and Twin Pulse firing sequence
New Ducati Panigale V4 to be unveiled November 5 at 9 p.m
“Marco Simoncelli” Misano World Circuit (Rimini, Italy), 7 September 2017 – Out of the experience gained in MotoGP, where the 4-cylinder Desmosedici unleashes incomparable performance, comes a new 90° V4 engine designed to power the Ducati supersport models of tomorrow. In transferring the technology of its most cutting-edge power unit from racetrack to road, Ducati offers customers performance levels honed by years of MotoGP experience.
Called the Desmosedici Stradale, this engine is set to become yet another Ducati milestone: it will be the first time ever that the Bologna-based motorcycle manufacturer has equipped a standard production bike with a 4-cylinder engine.
The official unveiling took place in Misano during the San Marino and Rimini Riviera GP, the thirteenth round of the 2017 MotoGP championship. A perfectly natural setting for the presentation, as MotoGP is the proving ground from which the new engine has drawn experience, technology and grit.
“It’s with undiluted pride that we unveil this technological gem. It represents the start of a new chapter for our company, underlining our vitality and an unshakeable commitment to investment in new products", stated Claudio Domenicali, Ducati CEO, during the presentation of the Desmosedici Stradale. "This engine also highlights the close collaboration between Ducati Corse and the factory bike development team, proving just how instrumental racing can be in developing the technology that is later applied on production bikes. In November, at EICMA, we’ll be showcasing the new Panigale V4, an all-new motorcycle powered by this extraordinary engine”.
While the Desmosedici Stradale engine is undoubtedly suited to the track, it has also been designed to respond to the needs of the road rider. For example, to maximise mid-range torque - essential for a satisfying road experience - and ensure punchy torque and power at lower revs, the engine has a slightly larger displacement than its MotoGP counterpart (1103 cm³, to be precise). Power output from the Euro 4 compliant engine configuration exceeds 155 kW (210 hp) at 13,000 rpm while maximum torque exceeds 120 Nm (12.2 Kgm) from 8,750 to 12,250 rpm.
An R version with a displacement of less than 1000 cc - which revs higher and is intended more for track use - is currently at the advanced development stage. This will provide the foundation for the homologated version that competes in the Superbike championship, where this engine will be used starting in 2019 (one year on from the launch of the respective road version, as per the Ducati tradition).
As on the Ducati bikes used in racing, the crankshaft is of the counter-rotating type. This reduces the overall gyroscopic effect and makes the bike faster and more agile when changing direction.
The crank pins, offset at 70° as on the Desmosedici GP, involve a Twin Pulse firing sequence that generates easy-to-handle power delivery and optimises out-of-the-corner traction (“Big Bang” effect). This firing sequence also gives the Desmosedici Stradale a unique signature sound.
A 90° V4 configuration makes the engine extremely compact, allowing centralisation of mass and smoothing incorporation on the vehicle. The Desmosedici Stradale has, in fact, been inserted on the motorcycle with the front cylinders banked 42° back from the horizontal, just like the Ducati engines employed in MotoGP. This, of course, optimises weight distribution, allows the adoption of larger radiators and brings the swingarm pivot point forwards.
Its architecture also evens up first order forces naturally without the added weight and power loss that a balancing countershaft would involve.
As in MotoGP, the engine was designed with an 81 mm cylinder bore. This measurement reflects the maximum limit allowed by MotoGP rules; it’s also the highest in the 4-cylinder supersport segment.
Using the same bore as the Desmosedici GP engine means both power units share nearly identical in-engine fluid dynamics (i.e. on valves, intake ducts and throttle bodies, right where the power is produced).
Needless to say, the new engine is designed around the Desmodromic system, a key characteristic that helps make Ducati prototypes the fastest in MotoGP. On this high-revving engine the “Desmo” system achieves a degree of sophistication, lightness and compactness never before seen on a Ducati.
Variable-height air intake horns constitute another first for a Ducati factory bike, optimising cylinder intake across the rev range and giving significant advantages in terms of 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 it.
This package of cutting-edge technical solutions - absolutely unique within the Supersport segment - makes the Desmosedici Stradale an engine like no other in the motorcycle world.
