What the Dafier filings say about the engines
Every Dafier filing on record is carburetted — 26 certificate rows, 2006 to 2015, and not one fuel-injected engine among them.
The engine codes on Dafier's test vehicles —8 distinct across the filings — are led by 139QMB, K172YMM, P157QMJ, 166FML and 152FMH. The code is stamped on the crankcase and is a better search term than the badge.
13 of the 26 filings are 50-state (California-legal); the other 13 were 49-state only.
Rated power across the range runs from 1.8 kW to 13.5 kW (about 2 to 18 hp).
The vehicle builders named are JINAN QINGQI MOTORCYCLE CO., LTD, Jinan Qingqi Motorcycle Co., Ltd., Jinan Qingqi Motorcycle Co., ltd. and Jinan Qingqi Motorcycle Co. Ltd. and others — 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.
