What the number itself says

Reading TSNGX.175AT2 left to right: T is the model-year letter for 2026, SNG is the three-character code the EPA assigned to Suyang Sports as certificate holder, X marks an off-road certification, .175 is the displacement in litres, so 175cc and AT2 is Suyang Sports' own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.

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.
