I have a SYM 180cc scooter made by San Yang Motors and I also ride one where possible when I visit Vietnam. Both are made in Taiwan and both are utterly reliable.
Japanese companies like Honda put a lot of their QA/QC expertise into Taiwanese companies to produce cars and motorcycles.
I also buy Taiwanese hand tools if I see them at the right price ,their steel quality is quite high.
I have complete faith in all things made in Taiwan.
A lot of Japanese companies use Thailand as their main plants for making their mid range vehicles.
