What the number itself says

Reading SSSTC.169MCE left to right: S is the model-year letter for 2025, SST is the three-character code the EPA assigned to Scooterstar Motors as certificate holder, C marks a highway (street-legal) certification, .169 is the displacement in litres, so 169cc and MCE is Scooterstar Motors' 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 Scooterstar Motors submitted for this family (model TANK-200EFI) carried engine code 1P61QMK-6. In the Chinese engine-model convention that reads as one cylinder, horizontal (flat) 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 7 kW (about 9 hp) at 6,500 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

Scooterstar Motors 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, Zhejiang Senling Motorcycle Co.Ltd. in China — engine and chassis from one source.

Certified emission levels: CO 2.2, HC 0.3 g/km.

Other records carrying the same engine code

Scooterstar Motors 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:

• TSSTC.169MCE (2026)

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.
