What the number itself says

Reading 9ZXMC.150SA1 left to right: 9 is the model-year letter for 2009, ZXM is the three-character code the EPA assigned to Zxmco Usa as certificate holder, C marks a highway (street-legal) certification, .150 is the displacement in litres, so 150cc and SA1 is Zxmco Usa'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
