A counter-rotating crankshaft offsets some of the gyroscopic effect generated by the spinning wheels which should result in quicker direction changes and greater resistance wheelies under acceleration or rear-wheel lift on decel – but the counter-rotation also requires a jackshaft to convert its spin into the proper direction for the final drive to the rear wheel.Ducati claims that extra shaft robs 0.98% from the crank, that’s a net loss of about two horsepower according to the boys from Bologna.Weighing in at 143 pounds, Ducati says the Desmosedici Stradale engine is only 4.9 lbs heavier than the last Panigale’s 1285cc Superquadro twin. The upper crankcase half incorporates four Nikasil-coated aluminum cylinder liners.

“Box in box” technology helps make the pistons superlight, while maintaining the necessary strength and stiffness to cope with the new V4’s incredible rpms and pressures.

Forged steel connecting rods measure 101.8mm center-to-center.

Each throttle body has one sub-butterfly injector for low-load use, and another shower-type injector above it that comes online as required.

Given the high revs attained by the V4 and the large valves, sayeth Ducati, a traditional spring system would be inadequate because the valves would be unable to follow the steep cam profiles.

the crankcase zone under the pistons is kept in a controlled, constant low-pressure state and thus reducing airing losses (i.e.

power absorption caused by the aerodynamic resistance exerted by the air and splashing of the oil in the con-rod casing).

Intake is via four oval, 52mm-equivalent throttle bodies with electronic variable intake lengths operating inside a big, 12.8-liter airbox.

There’s a fixed funnel on each throttle body plus a sliding upper funnel that an electric motor moves along steel guides, for a broader powerband.

That optimizes weight distribution, leaves room for larger radiators, and brings the swingarm pivot as far forward as possible.

The main engine mounts are attached to the front of the upper crankcase half and to the rear cylinder head.

This is where the Desmodromic system becomes a must.
