V4 Granturismo

The perfect blend of performance, lightness and overall dimensions. For a more compact engine yet still capable of delivering progressive power at different speeds, and the ideal drive and impetus on demand in all riding conditions.

A higher delivery than that of the previous Testastretta DVT, which highlights the sporting spirit of this bike and boosts its range of performance. A great torque, on demand at all speeds, and with progressive, slick and smooth delivery.

The 6-gear engine is optimised to exploit the exceptional power of the engine torque and ensure the ideal response even when carrying a passenger and at full load.

The diameters and lengths of the tubes have been specially designed to provide the best possible road delivery. The V4 Granturismo throttle bodies are controlled by a dedicated electric motor and can activate the throttles in an asynchronous mode between the two banks. This makes it possible to accomplish a positive power delivery curve at all speeds and a smooth torque which adds to achieving maximum on-road riding pleasure.

The know-how developed on the desmodromic system, applied to the spring timing system, has made it possible to extend the valve clearance maintenance schedule to 60,000 km, compared to a sector average of 25,000, hence less than half.

Maintenance operations are reduced both in terms of costs and frequency; even the oil service and the mileage service are scheduled at very long intervals, 15,000 km and two years respectively.

The 70° offset of the crank pins combined with the 90° V-engine layout generates a firing order that Ducati has called "Twin Pulse". The result is a sound that is similar to that of a twin-cylinder engine, but also a superb delivery at all speeds, and easy to manage, especially when coming out of a bend.

The refining of the sound performed on the engine components, has made it possible to recreate the emotion of the typical Ducati sound and an exceptional riding comfort, with volumes and frequencies that minimise disturbance for both rider and passenger, especially on long journeys.

The rear cylinder deactivation, again taken from the Desmosedici Stradale model, is triggered when the engine is running at low speed, shutting off the rear bank, the one closest to the seat, improving comfort for both rider and passenger, thanks to the decrease in temperatures whilst optimising consumptions.

The adoption of the counter-rotating crankshaft - borrowed from MotoGP - makes it possible to reduce the gyroscopic effect of the wheels on the vehicle, boosting handling and agility and reducing pitching when accelerating and braking. This technical choice improves both safety and riding comfort, not just on the track but also and especially for daily road use or when travelling at full load.

The four camshafts of the V4 Granturismo engine exploit the rocker arms and move the 16 steel valves, the intake valves having a diameter of 33.5 mm and the exhaust valves measuring 26.8 mm in diameter.

Like the Desmosedici Stradale, the V4 Granturismo engine uses a semi-dry casing lubrication with delivery and recovery stages to ensure proper lubrication of all moving parts at all times. A technical choice first used on the race track, but ideal for ensuring maximum reliability to a road engine that also required excellent lubrication in all situations. The “high” oil sump also contributes significantly to the increase in ground clearance, excellent for urban and off-road use

The water pump, located in the V of the cylinders, is powered by a shaft driven by a cascade of gear wheels. Its location is designed to reduce the size of the circuit as much as possible, improving its efficiency and optimising engine weight.
