The Bologna, Italy based superbike maker, Ducati has recently unveiled its new age V4 engine which is named as the Desmosedici Stardale. It gets its name from its Ducati MotoGP bike from which it has essentially taken birth. It is about to change the way world look at Ducati superbikes and why is that? It’s because for the first time the company has given one of its mass production superbikes a V4 engine.
What about the Desmosedici RR superbike?
While in the past, there was one of the Ducati icons which was road legal and came with a V4 engine, the Desmosedici RR but it was a limited edition bike and was only available for the lucky ones and hence was never produced for masses.
How is it different from the current engines?
Ducati has recently risen the bar in the MotoGP championship and is constantly improving on all grounds, and hence it is obvious to take inspiration from it and utilize it into making its road bikes better.
· The V4 configuration:
The new Stradale engine is V4 unlike the previous V-Twin engine on the 1299 Panigale which has been taken off the list now. The company started off with the design of the Stradale from the heart of the GP engine which is its cylinder head design. What keeps this engine compact is the fact that it borrows the same dimensions too, the 90-degree V4 unit gets a backward 42-degree rotation. And the company doesn’t need a countershaft to balance the engine since it maintains the 90-degree V-angle.
· Counter-rotating crankshaft:
The counter-rotating crankshaft has been carried on from the GP, it helps the engine by reducing the gyroscopic forces to a minimum, improving the overall agility and handling dynamics of the bike. This also aids in limiting the wheelie effect under hard acceleration and on the rear end it controls the rear wheel lift when the bike is brought to halt.
· Firing order:
The Stradale runs on a ‘twin-pulse’ firing sequence that also contributes to one of the unique sounds ever from a motorcycle, and that’s also because it’s crank has a 70-degree offset. Both the left cylinders get fired up very closely followed by the opposite cylinders and its firing order of 0-90-290-380 turns it into a huge twin.
How powerful is this engine?
The company has quoted that even though it is fully race derived, it will as good to ride on the streets as it is on the tracks. Ducati has pumped the displacement to 1103cc and this has been achieved by increasing the stroke while maintaining the same bore as the maximum permitted in a GP bike, which is 81mm. All this has resulted in a stronger low-end torque and punchier power delivery. The engine is capable of producing ground shaking 210hp at 13,000rpm, while peak torque of 119.3Nm comes between 8750 to 12,250rpm.
It is clear that the engine has grown complex big time but all that complexity doesn’t bring any changes in the service interval timing or valve inspection service intervals. As stated by Ducati, the regular service timing for this engine is 12months or 7500 miles while 15000 miles is the valve inspection service interval.
