What the Scootstar filings say about the engines
Every Scootstar filing on record is carburetted — 5 certificate rows, 2019 to 2023, and not one fuel-injected engine among them.
None of the 5 filings is a 50-state certification: these were sold as 49-state machines, not certified for California.
Rated power on the record is 2.2 kW (about 3 hp).
The vehicle builders named are Taizhou Zhongneng Motorcycle Co., Ltd. and Taizhou Zhongneng Motorcycle 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.
