What the number itself says
Reading CPPSC.049S4A left to right: C is the model-year letter for 2012, PPS is the three-character code the EPA assigned to Peace Power Sports as certificate holder, C marks a highway (street-legal) certification, .049 is the displacement in litres, so 49cc and S4A is Peace Power Sports' own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.
