What the number itself says

Reading BDFRC.150QQA left to right: B is the model-year letter for 2011, DFR is the three-character code the EPA assigned to Dafier as certificate holder, C marks a highway (street-legal) certification, .150 is the displacement in litres, so 150cc and QQA is Dafier'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 Dafier submitted for this family (model QM150T-10H) carried engine code P157QMJ. In the Chinese engine-model convention that reads as one cylinder with a nominal 57 mm bore, QMJ 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 6 kW (about 8 hp) at 7,000 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

Dafier filed one certificate under this family, for model year 2011, sold as 50-state, California included.

The vehicle itself is recorded as built by the same company, JINAN QINGQI MOTORCYCLE CO., LTD in China — engine and chassis from one source.

Certified emission levels: CO 0.7, HC 0.2 g/km.

Other records carrying the same engine code

Dafier certified an engine with this code under 2 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

• 9DFRC.150QQA (2009)
• ADFRC.150QQA (2010)

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.

Every model designation the importer listed on this certificate. If your machine's model name appears here, this is the right record — even if the name on the bodywork is slightly different.
