Ducati has unveiled its newly designed V4 Gran Turismo engine. This engine will be used in the new Multistrada V4, which made its world premiere on November 4.
The V4 Gran Turismo engine is extremely compact and light, with powerful torque. Developed to meet the needs of the most demanding "adventure touring", this engine is the perfect combination of thrilling driving and sporty feeling.
Maximum smooth operation and record long maintenance intervals (60,000km).

From the following press release
Ducati V4 Gran Turismo Engine
The valve actuation system is a spring valve return system with an excellent maintenance interval (60,000 km). This figure has been achieved by drawing on Ducati's extensive expertise in the development of materials, finishing treatments, and technical solutions developed around the Desmodromic system.
This expertise was applied to the valve spring return system, which places less stress on components than the Desmodromic, achieving a milestone of exceptional excellence for a motorcycle engine. The engine is also characterized by its extremely smooth operation, especially at low revs. At the same time, it delivers the same performance, high-revving power, and top speed as a full-fledged sports engine. The V4 Gran Turismo has a maximum output of 170ps (125kW) @ 10,500rpm and a maximum torque of 125Nm (12.7kgm) @ 8,750rpm. This engine complies with the strict Euro 5 regulations.
Weighing only 66.7 kg, it is 1.2 kg lighter than the Testastretta two-cylinder engine used in the Multistrada 1260. 1,158 cc displacement was chosen to meet all the performance, weight, and dimensional requirements of a V4 engine, making it an extremely light and compact unit. The displacement is set at 1,158cc to meet all the performance, weight, and dimensional requirements of a V4 engine, resulting in a very light and compact unit.
When compared to the engine of its predecessor, the V4 Gran Turismo's dimensions are 85 mm shorter, 95 mm lower, and 20 mm wider. The compact layout has allowed Ducati engineers to mount the engine in a more ideal position in the center of the frame, with a positive effect on the motorcycle's center of gravity.
The V4 Gran Turismo incorporates many of the technologies that Ducati has developed in the world of racing. One example is the counter-rotating crankshaft. This crankshaft improves handling and agility and reduces pitching under acceleration. The 'Twinpulse' technology, which delivers strong torque and smooth operation, also draws feedback from the racing world.
The V4 Gran Turismo has a function that deactivates the rear banking when the car is idling to prevent the heat generated by the rear cylinders from reducing comfort. This allows the rear bank to deactivate when the motorcycle is stopped, stopping the combustion process in the cylinders and improving rider and passenger comfort by reducing engine temperature while reducing fuel consumption.
