What the number itself says

Reading 7GDHX.125DM3 left to right: 7 is the model-year letter for 2007, GDH is the three-character code the EPA assigned to Golden Horse Vehicle Usa as certificate holder, X marks an off-road certification, .125 is the displacement in litres, so 125cc and DM3 is Golden Horse Vehicle 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

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).

Rated power on the record is 5.6 kW (about 8 hp) at 7,500 rpm, driving through a 3-speed manual gearbox.
