What the number itself says
Reading PBYMC.223MC1 left to right: P is the model-year letter for 2023, BYM is the three-character code the EPA assigned to Benyate Motorsport as certificate holder, C marks a highway (street-legal) certification, .223 is the displacement in litres, so 223cc and MC1 is Benyate Motorsport'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 Benyate Motorsport submitted for this family (model FY250-4) carried engine code 165FMM. In the Chinese engine-model convention that reads as one cylinder with a nominal 65 mm bore, FMM series. Against the certified 223cc that implies a stroke of roughly 67 mm — a sanity check for a piston or cylinder listing, not a published figure.
The certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by throttle-body fuel injection, with an oxygen sensor for closed-loop fuelling, run by an engine control module (ECM). No catalytic converter is listed.
Rated power on the record is 11.5 kW (about 15 hp) at 7,500 rpm, driving through a 6-speed manual gearbox.

Filing history and where it was sold
Benyate Motorsport filed one certificate under this family, for model year 2023, sold as 50-state, California included.
The vehicle itself is recorded as built by Taizhou Qianxin Vehicle Co,.Ltd in China, while the engine came from Chongqing Zongshen. Chassis parts and engine parts therefore have different origins.
Certified emission levels: CO 3.3, HC 0.5 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.
