Define "third world country" ?
If by that you mean India, then that lets out KTMs under 400cc, the BMW 310 models & the small Triumphs being mooted as well as the REs.
If you include Thailand in that description, then you can also exclude some Hondas, Kawasakis & most other Triumphs (and possibly others).
How about Brazil ? Honda make some models there.
BMWs parallel twin engines are made in PRC. etc. etc.
Motorcycle & car production is a global affair - my wife's first Hyundai i20 was made in India, her i10 was made in the Czech Republic & her new i20 in Turkey despite Hyundai being a Korean company.
