Who actually makes Yiying Motorcycle Inc.?

What the Yiying Motorcycle filings say about the engines

Every Yiying Motorcycle filing on record is carburetted — 16 certificate rows, 2009 to 2015, and not one fuel-injected engine among them.

The engine codes on Yiying Motorcycle's test vehicles —3 distinct across the filings — are led by BZ157QMJ, BZ139QMB and BZ173MN. The code is stamped on the crankcase and is a better search term than the badge.

7 of the 16 filings are 50-state (California-legal); the other 9 were 49-state only.

Rated power across the range runs from 2.2 kW to 13.5 kW (about 3 to 18 hp).

The vehicle builders named are Benzhou Vehicle Industry Group Co.,Ltd. and Benzhou Vehicle Industry Group 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.
