for our friends in another part of the world, those supercub kind of motorcycles (with semi-automatic gear/without clutch) are popular in third world country in Asia, for some people there those are Limousines (literally 4 to 5 people riding it lol)
though in recent years its popularity was dwindling and replaced by scooter (CVT/no gear) 'cause everybody (yes, including toddler) can ride them
in many countries outside Japan the 50cc motorcycle/scooter AFAIK isn't popular, ppl prefer 100~200cc for low to middle income individual/families, 250cc and up is usually for middle class, 500cc and up is for the rich, 750cc+ and Harley Davidson are for the super rich only lol
