That's probably the reason - we only need dressage horses and pure bloods now that the real draft horse is getting put to pasture.
These are no longer workhorses.
Six cylinders are the smoothest engines out there.
Honda used to have a 1L 6 cylinder engine for their bikes - the Gold wing has a 6 cylinder still.
The perimeter of the piston goes down in relation to its area (& multiplied by BMEP) when the radius goes up - looking at you Africa Twin.
The perimeter is where the unburnt fuel lives and gets caught up in the emission rules. So fewer larger cylinders is better according to EPA - 500cc each, maybe.
If we're only going to have hobby vehicles with internal combustion, then a six cylinder or doubling up to a v-12 makes sense.
They're toys for the weekend, not to put a 100k miles on it.

I dunno man, have you ever driven a rotary? The design has a lot of problems, but smoothness isn't one of them...
