Barry, I read the links, I get it. What does it have to do with GP?
Damn near nothing.
What Barry had steadfastly refused to acknowledge, much less address, is the fact that 'The piston giveth back all that it taketh away.'
Assuming forward leading cylinders, located forward of the bike's center of yaw...
Yes, as the piston and con-rod move forward, they will steal a small fraction of the bike's rotational energy.
This is just basic conservation of (rotational) momentum, or 'Coriolis force.'
When the same piston and con rod, now holding more rotational momentum, moves rearward on a downstroke, it
will transfer that borrowed rotational energy back into the engine. This will make the bike want to turn faster, not slower.
There is no persistent 'gyro' effect that resists the yawing of the bike.
In the worst case, with one big piston pointing straight ahead, the engine would see small, high frequency, lateral torque pulses occurring at hundreds of Hz. With a rigidly mounted engine and a huge, long throw piston, enough of this noise might reach the chassis to cause handling issues.
However, the Ducati has not one, but TWO inclined pistons (and two vertical.) The two pistons within each bank are light, travel less than two inches and, most importantly, are very likely to be operating 180 degrees out of phase with one another. (The timing between the two banks is less clear, and is probably varies to deliver more or less 'big bang' effect.) If this is the case, the two pistons will trade rotational energy between them and very, very little of this potential yaw-torque-pulsing will ever touch the chassis. IMO, Barry's 'VSGs inhibit the bike's turning ability' argument is not based in reality.
