What the number itself says

Reading TGWIX.120ATA left to right: T is the model-year letter for 2026, GWI is the three-character code the EPA assigned to Golden Wing Industry as certificate holder, X marks an off-road certification, .120 is the displacement in litres, so 120cc and ATA is Golden Wing Industry's own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.

The engine, as described on the certificate

Filing history and where it was sold

Golden Wing Industry filed one certificate under this family, for model year 2026, sold as 49-state (not certified for sale in California).

The vehicle itself is recorded as built by Viet Trung International Development Joint Stock Company in Vietnam, while the engine came from Chongqing Xingfenghong Technology Co.,Ltd. Chassis parts and engine parts therefore have different origins.

Certified emission levels: CO 14, HC+NOx 1.1 g/km.

A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
