What the number itself says
Reading 9SUNC.150SAA left to right: 9 is the model-year letter for 2009, SUN is the three-character code the EPA assigned to SunL Group as certificate holder, C marks a highway (street-legal) certification, .150 is the displacement in litres, so 150cc and SAA is SunL Group's own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.
