What the Jiangsu Sacin Usa filings say about the engines
Every Jiangsu Sacin Usa filing on record is carburetted — 4 certificate rows, 2021 to 2024, and not one fuel-injected engine among them.
The engine codes on Jiangsu Sacin Usa's test vehicles —just one across the filings — are led by 139FMA-2. The code is stamped on the crankcase and is a better search term than the badge.
All 4 filings are 50-state certifications, so every one of these machines was certified for sale in California.
Rated power on the record is 1.8 kW (about 2 hp).
The vehicle builder named on every row is Jiangsu Sacin Motorcycle Co., Ltd.
Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.
