I have a 2012 Chinese made KYMCO LIKE200i purchased new in 2013.
It runs fine, and I've found no issues where the build quality might have been better if made in Taiwan.
We have no idea how much KYMCO is looking on as these scoots are assembled in China.
However, the scooter is warrantied by KYMCO for 2 years - no other Asian 2-wheeled anything carries more than a one year warranty. (that I am aware of)
Will you be running that scooter more than two years? Keep it stock, document & follow the maintenance schedule....and run the heck out of it.
2 wheel Hondas are made in Thailand, Vietnam, Italy, & I think India. And some in Japan. Honda cars are assembled in Ohio - and they're still OK !!
Stick with a trusted brand - and maybe don't be too worried about the assembly point....especially if it comes with a killer warranty.
Just my opinion.
