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.
