What the Sunbeam Motorsports filings say about the engines
Every Sunbeam Motorsports filing on record is carburetted — 2 certificate rows, 2009, and not one fuel-injected engine among them.
The engine codes on Sunbeam Motorsports' test vehicles —2 distinct across the filings — are led by FT1390MB and BN157QMJ. The code is stamped on the crankcase and is a better search term than the badge.
1 of the 2 filings are 50-state (California-legal); the other 1 were 49-state only.
Rated power across the range runs from 2 kW to 6.2 kW (about 3 to 8 hp).
The vehicle builders named are Taizhou Zhongneng Motorcycle Co.,Ltd. and Sunbeam Motorsports Inc. — 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.
