What the Hi-Bird Motorcycle USA filings say about the engines
Every Hi-Bird Motorcycle USA filing on record is carburetted — 16 certificate rows, 2006 to 2010, and not one fuel-injected engine among them.
The engine codes on Hi-Bird Motorcycle USA's test vehicles —6 distinct across the filings — are led by HBMC-198, HBM-CI-125, HBM-ATV-198, HBM-ATV-248 and HBMC-233. The code is stamped on the crankcase and is a better search term than the badge.
8 of the 16 filings are 50-state (California-legal); the other 8 were 49-state only.
Rated power across the range runs from 7 kW to 13.3 kW (about 9 to 18 hp).
The vehicle builders named are CHONGQING HI-BIRD MOTORCYCLE INDUSTRY CO LTD and CHONGQING HI-BIRD MOTORYCLE INDUSTRY 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.
