Certificate numbers

SYGMC.169MCA-004

What the number itself says

Reading SYGMC.169MCA left to right: S is the model-year letter for 2025, YGM is the three-character code the EPA assigned to Yuluo Global Motor as certificate holder, C marks a highway (street-legal) certification, .169 is the displacement in litres, so 169cc and MCA is Yuluo Global Motor'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 Yuluo Global Motor submitted for this family (model STRIKER 200) carried engine code YN1P61QMK. In the Chinese engine-model convention that reads as one cylinder, horizontal (flat) cylinder, with a nominal 61 mm bore, QMK series. Against the certified 169cc that implies a stroke of roughly 58 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 8.3 kW (about 11 hp) at 7,000 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

Yuluo Global Motor filed one certificate under this family, for model year 2025, sold as 50-state, California included.

The vehicle itself is recorded as built by the same company, Sanmen County Yongfu Machine Co,.Ltd in China — engine and chassis from one source.

Certified emission levels: CO 3.1, HC 0.4 g/km.

Other records carrying the same engine code

Yuluo Global Motor certified an engine with this code under one other family number — the same engine filed again in another year, or in an off-road and a street version:

• RYGMC.169MCA (2024)

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.
