Which Zhiwei Motorcycle(USA) models have a Chinese-built engine?

What the Zhiwei Motorcycle(USA) filings say about the engines

Every Zhiwei Motorcycle(USA) filing on record is carburetted — 16 certificate rows, 2018 to 2026, and not one fuel-injected engine among them.

The engine codes on Zhiwei Motorcycle(USA)'s test vehicles —2 distinct across the filings — are led by 1P39QMB and 161QMK. The code is stamped on the crankcase and is a better search term than the badge.

1 of the 16 filings are 50-state (California-legal); the other 15 were 49-state only.

Rated power across the range runs from 1.8 kW to 7.8 kW (about 2 to 10 hp).

The vehicle builders named are Taizhou Jiaojiang Zhiwei Motorcycle Manufacture Co., Ltd. and Taizhou Jiaojiang Zhiwei Motorcyele Manufacture Co., Ltd. — the chassis and the engine do not always share a source.

Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.

The factory changed. Here is when.
