Finally pulling the covers off the rumoured V-four that was in development, Ducati unveiled its new four-cylinder Desmosedici Stradale engine, which will see its first appearance in a new Panigale superbike. The 90-degree V-four was developed from the Desmosedici MotoGP machine, first campaigned in 2003.

With an emphasis on mid-range torque, the new engine displaces 1,103 cc, with a 14:1 compression ratio, and is Euro 4 compliant. Power figures from the mill are 210 hp at 13,000 rpm and 120 Nm of torque from 8,750 to 12,250 rpm.

Also in the works is an ‘R’ version of the Desmosedici Stradale, coming in below 1,000 cc as per World Superbike Championship (WSBK) rules, and with a redline of 13,000 rpm. The power plant will be submitted for homologation and is expected to hit the circuits in 2019.

Using a “Twin Pulse” firing sequence, where the cylinders fire at 90-200-90-340 degrees, the new V-four uses a counter-rotating crankshaft that reduces gyroscopic effect and allows for quicker changes of direction. Although the power pulses occur close together and can overwhelm rear tyre traction, the slight pause in the power pulses also makes a rear slide easier to catch.

With the V-four engine configuration evening up first order moments internally, the need for a counter-balancer shaft is eliminated, reducing weight and power loss. Taking many cues from the MotoGP Desmosedici engine, the Stradale version also comes with valves, intake ducts and throttle bodies taken of the race power plant, along with variable height intake horns.

Standard are oval throttle bodies, the equivalent of 52 mm diameter conventional units, with twin injectors. These are located above and below the throttle butterfly, to optimise both low- and high-speed fuelling.

Ducati’s Desmodromic valve actuation is also part of the package, driven by a hybrid belt/gear system to ensure proper valve opening and closing at racing speeds. For lubrication a semi-dry sump is used, and one delivery and three return oil pumps ensure the engine is adequately lubricated.

Completing the package is a six-speed gearbox, with Ducati up- and down-quickshifting, along with a wet-plate anti-patter servo clutch. Maintenance interval on the Desmosedici Stradale is claimed to be 24,000 km.
