As other posters have commented already there are companies that do not really manufacture motorcycles from the ground up themselves. Instead these companies assemble motorcycles, buying off the shelf parts made by other companies that manufacture various components. It's a huge business model, and there are lots of these specialised manufacturers throughout China though most are centred around ChongQing, where 50% of Chinese motorcycle manufacturing is concentrated. On the China side, I personally have never seen these bikes, which is not to say they aren't available, just that if they are maybe they can only bought on Alibaba (which is a selling platform for international trade) versus Taobao (which concentrates on domestic sales). The bikes might be available through a "normal" bricks and mortar store, but more likely a small enterprise. Certainly I've not seen any at my local neighbourhood motorcycle shops.

This means it's highly likely that these bikes have little in the way of R&D and little to no follow up or after sales support. Even if they do it won't be smooth sailing. Oh, and please don't place too much reliance on photos, because in China photos are easy to come by and are really easily manipulated or staged. Better yet photos are often stolen and altered to suit the purpose. The only way to know for yourself is to see it first hand with your own two eyes, see behind the charades, speak the language, understand the cultural mindset and then divide the result by half.

For nothing in China is what it seems, everything is just for looking, beAware the smoke and mirrors - my proverb.

YMMV
