What the number itself says

Reading LAPSX.124VA1 left to right: L is the model-year letter for 2020, APS is the three-character code the EPA assigned to Apollo Motorsports Usa as certificate holder, X marks an off-road certification, .124 is the displacement in litres, so 124cc and VA1 is Apollo Motorsports 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 test vehicle Apollo Motorsports Usa submitted for this family (model VRX125) carried engine code 154FMI. In the Chinese engine-model convention that reads as one cylinder with a nominal 54 mm bore, FMI 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 6.3 kW (about 8 hp) at 7,500 rpm, driving through a 4-speed automatic.

Filing history and where it was sold

Apollo Motorsports Usa filed one certificate under this family, for model year 2020, sold as 49-state (not certified for sale in California).

The vehicle itself is recorded as built by Zhejiang Apollo Motorcycle Manufacturer Co., Ltd. in China, while the engine came from Chongqing Zongshen. Chassis parts and engine parts therefore have different origins.

Certified emission levels: CO 3.1, HC+NOx 0.7 g/km.

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.
