Without reading too much of it (I'm on my phone) my guess would be its referencing the bending moment of the crank.

I may be wrong but I believe in this case it is using the opposite rotation of the crankshafts and inertia created from them to cancel each other out. Same way that equal and opposite sound waves cancel each other out.

What’s “moment-canceling?” One of the things that strongly affects a motorcycle’s resistance to roll maneuvers (“flickability”) is flywheel gyroscopic moment. Just as the gyro moments of Yamaha’s twin-crank YZR500s canceled each other, so do those of Gurney’s new big twin.

Thats pretty cool, thanx for the explanation.
