What the number itself says

Reading RBYMC.168MCA left to right: R is the model-year letter for 2024, BYM is the three-character code the EPA assigned to Benyate Motorsport as certificate holder, C marks a highway (street-legal) certification, .168 is the displacement in litres, so 168cc and MCA 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 FY200T-22) carried engine code 161QMK. In the Chinese engine-model convention that reads as one cylinder with a nominal 61 mm bore, QMK series.

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 6.8 kW (about 9 hp) at 8,000 rpm, driving through a CVT (belt and variator).

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.
