Actually I think the reverse rotating cranks didn't work very good, and at least some of the counter rotating crank bikes did okay.
As far as I remember, the MCyz has a mostly standard I4. It lies in the frame longways instead of across. Never heard of a counter- or revers- rotating crank. Spinning the engine the opposite direction wouldn't change anything except one gearset in the transmission.

BMW has some bizarre conterbalancing schemes though. The 800GS has a weird levered counterweight thing the crank forces down on the piston upstroke.

While I think it runs long ways, I think it also has 2 cranks which spin opposite ways.

As for not changing anything with the crank spinning backwards, ever pay attention to the freestyle guys, and how they use the throttle to either lift or drop the front end? The same forces happen whether the bike is in the air or on the ground.

As well as there are a number of yamaha engines that had 2 cranks, which iirc at least some of them had cranks that spin opposite each other.

The square 4 engines had 2 cranks.

exactly, the cyz has counter rotating cranks. Ought to be a very neutral bike. Doubt he'll ever make them affordable though
