What the number itself says

Reading 9ESYX.110AAA left to right: 9 is the model-year letter for 2009, ESY is the three-character code the EPA assigned to Easy Vehicle as certificate holder, X marks an off-road certification, .110 is the displacement in litres, so 110cc and AAA is Easy Vehicle'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 test vehicle Easy Vehicle submitted for this family (model YL808 (YH110D)) carried engine code 152FMH. In the Chinese engine-model convention that reads as one cylinder with a nominal 52 mm bore, FMH series.

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). No catalytic converter is listed.

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

A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
