Ducati Introduces V4 Granturismo Engine For Next-gen Multistrada

Ducati has unveiled the new V4 Granturismo engine for the next generation of Ducati Multistrada. It is said to be an extremely compact, lightweight, high-performance, torque-rich engine designed to meet the needs required in ‘adventouring’ use.

Ducati has guaranteed first in class materials that would deliver durability and reliability. The V4 Granturismo project is said to have been undertaken with the aim of ensuring maximum fluidity of operation combined with a substantial extension of maintenance intervals. The new distribution includes a spring valve return system, that brings the maintenance intervals of the V4 Granturismo to 60,000 km. Figures have been obtained thanks to the in-depth expertise Ducati acquired in the use of materials, treatments and technical solutions developed around the Desmodromic system (refers to the way that a poppet valve inside of an engine is controlled).

Ducati claims that the new spring valve return system gives less stress to the components, if compared to the Desmo and thus, has achieved an outstanding milestone never set before by a motorcycle engine. The engine is said to ensure great regularity of operation at low revs and low loads while maintaining outright performance, power at high revs and the reach of an authentic sports engine. The V4 Granturismo delivers 125 kW (170 hp) of power at 10,500 rpm and a maximum torque of 125 Nm at 8,750 rpm. The new engine also comes with a counter-rotating crankshaft for improved handling and agility and exploits the ‘Twin Pulse’ technology that offers a full-bodied but perfectly manageable power delivery at every speed. It also adopts the strategy of deactivating the rear bank at idle. In this way, when the bike is stationary, the combustion process in the cylinders is halted and this improves the thermal comfort of the rider and passenger thanks to the lowering of temperatures while simultaneously reducing fuel consumption. All this is achieved while adhering to the stringent Euro 5 homologation norms.

The new V4 Granturismo engine is reportedly 1.2 kg lighter (with 66.7 kg) than the Testastretta twin-cylinder used on the previous Multistrada 1260. The 1,158 cc displacement engine is 85mm shorter, 95mm lower and only 20mm wider. This compact layout allowed Ducati engineers to house the engine in the frame more effectively and centrally in order to positively influence the position of the bike's center of gravity, with all the resulting benefits.
