What the number itself says

Reading 9VCOX.125DMA left to right: 9 is the model-year letter for 2009, VCO is the three-character code the EPA assigned to Vicoo Industry as certificate holder, X marks an off-road certification, .125 is the displacement in litres, so 125cc and DMA is Vicoo Industry'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

The certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by carburettor, run by an ignition control module (CDI-type ignition). There is a catalytic converter in the exhaust, recorded as "TWC, single bed, open loop".
