Sym international models are not exactly the same as those sold in Sym Taiwan. If you look up the Husky you would find all Chinese content made only in China, likely not sold in Taiwan itself.

One good example would be the Sym Naga 155 recently launched, there are two variants of it. The one in Taiwan (called MMBCU) is the best-selling scooter in Taiwan for years, and comes with a 158cc engine. The one sold in ASEAN + China come with 150cc and are made in China by Xiashing Motorcycle, and there are plenty of comparisons between them in China with the Taiwanese version coming out on top, of course price is also about 10K yuan more expensive.

China variants typically have worse QC, even though they are somehow still more reliable, likely the R&D is done within Taiwan or at least had to go through some approval process in headquarter.
