What the number itself says

Reading 8YGGX.250AMA left to right: 8 is the model-year letter for 2008, YGG is the three-character code the EPA assigned to Yongjiang Motors as certificate holder, X marks an off-road certification, .250 is the displacement in litres, so 250cc and AMA is Yongjiang Motors' own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.
