What this record says

Sold in the US by: American Chite Technology LLC
Engine built by: Taizhou Qianxin Vehicle Co,.Ltd
Vehicle category: Highway Motorcycle - Ib (50-169cc)
Certificate numbers: TACTC.168MCA-002

What the number itself says

Reading TACTC.168MCA left to right: T is the model-year letter for 2026, ACT is the three-character code the EPA assigned to American Chite Technology as certificate holder, C marks a highway (street-legal) certification, .168 is the displacement in litres, so 168cc and MCA is American Chite Technology'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 American Chite Technology submitted for this family (model SABER-200) 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 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 6.8 kW (about 9 hp) at 8,000 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

American Chite Technology filed one certificate under this family, for model year 2026, sold as 50-state, California included.

The vehicle itself is recorded as built by Zhejiang Guangchuangxin Energy Technology Co.,Ltd in China, while the engine came from Taizhou Qianxin Vehicle Co,.Ltd. Chassis parts and engine parts therefore have different origins.

Certified emission levels: CO 5.5, HC 0.4 g/km.

What this configuration means when you shop for parts

American Chite Technology certified the 161QMK 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 before ordering.

The CVT behind the 161QMK makes its drive belt, variator rollers and clutch shoes the consumables, so measure the old belt on the SABER-200 rather than ordering by displacement.

The PAIR valve American Chite Technology lists on the 161QMK is an emissions part; its hoses perish and are the usual cause of popping on the overrun.

The exhaust on American Chite Technology's TACTC.168MCA carries a catalyst, so a replacement silencer without one changes what the 161QMK 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.
