What the number itself says
Reading 7SIAX.300AA1 left to right: 7 is the model-year letter for 2007, SIA is the three-character code the EPA assigned to Sunright International of America as certificate holder, X marks an off-road certification, .300 is the displacement in litres, so 300cc and AA1 is Sunright International of America's own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.
