Seems like somebody did get caught into the spitting contest, and now needs to wipe his face
Back to bikes...
Many Countries "force" specific mechanical or marketing characteristics, in such a way to control their domestic marlet.
Japan, for example, taxes bikes over 400cc to death, so that they become extraordinarily expensive.
So many 750/900cc models we have are only seen in their 400cc variant in Japan.
See Honda CBX, Honda VFF, Yamahas XJ etc.
Guzzi sold its "V35/V50" air cooled twin as the "V40" for the japanese market only.
Similarly... in Sweden nobody would ever consider buying a car not equipped with an engine heater or a heated windshield; in the Mediterranean area these would be redundant, but you'd want metallic paint to keep the heat down in the hot summers.
In some places you'd welcome warm velvet upholstery, elsewhere it's synthetic fabric or leather because velvet is needlessly hot.
Back to bikes: 400cc twins are excellent commuter/utility bikes, and were considered "quite good" in 19702/1980's Europe.
These days you need a 1000cc behemoth to commute to work - that or a CVT 250cc scooter.
Back in the day, most bikes shared very much the same architecture:
OHV (pushrod) single or twins, air cooled, drum brakes and c comfortable cruising speed anywhere from 50 to 70mph.
They all had kick start and points&condenser ignition.
...And they all leaked oil somehow or other
Enter Honda.
For whatever engineering strategy, Hondas were OHC twins when their European counterparts were OHV.
For whatever engineering strategy, Hondas were often undersquare and would rev higher than their European OHV counterparts.
For whatever engineering strategy, Hondas were often equipped with a 5 speed gearbox when their European OHV counterparts.
For whatever engineering strategy, Hondas were equipped with CDI ignition when their European counterparts still relied on points&condenser.
The result is that even the "humble" Honda CB 302 looked "more bike" than the average European 350 counterpart

When Honda first came out with its CB 750 Four, it was a revelation.
Or, as others put it, a Revelation, meaning the
Apocalypse of Old World motorcycling.
