What this record says

Sold in the US by: Dongfang Motor, Inc.
Engine built by: Ningbo Dongfang Lingyun Vehicle Made Co., Ltd.
Vehicle category: Highway Motorcycle - Ib (50-169cc)
Certificate numbers: FDGFC.169DF2-001

What the number itself says

Reading FDGFC.169DF2 left to right: F is the model-year letter for 2015, DGF is the three-character code the EPA assigned to Dongfang Motor as certificate holder, C marks a highway (street-legal) certification, .169 is the displacement in litres, so 169cc and DF2 is Dongfang 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 Dongfang Motor submitted for this family (model DF200TKB) carried engine code 161QMK-A. 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 carburettor. There is a catalytic converter in the exhaust, recorded as "TWC, single bed, open loop". The head carries a pulse secondary-air (PAIR) valve.

Rated power on the record is 7.6 kW (about 10 hp) at 7,000 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

Dongfang Motor filed one certificate under this family, for model year 2015, sold as 49-state (not certified for sale in California).

The vehicle itself is recorded as built by the same company, Ningbo Dongfang Lingyun Vehicle Made Co., Ltd. in China — engine and chassis from one source.

Certified emission levels: CO 10.5, HC 0.6 g/km.

What this configuration means when you shop for parts

Dongfang Motor certified the 161QMK-A with a carburettor, so the fuel-side wear items are the carburettor, its jets and float needle, the intake boot and the choke. The 61 mm bore in the code gives the engine size, not the carburettor size — measure the intake bore and the mounting on the 161QMK-A before ordering.

The CVT behind the 161QMK-A makes its drive belt, variator rollers and clutch shoes the consumables, so measure the old belt on the DF200TKB rather than ordering by displacement.

The PAIR valve Dongfang Motor lists on the 161QMK-A is an emissions part; its hoses perish and are the usual cause of popping on the overrun.

The exhaust on Dongfang Motor's FDGFC.169DF2 carries a catalyst, so a replacement silencer without one changes what the 161QMK-A was certified with.

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.
