Who actually makes Speed Utv, LLC?

What the Speed Utv filings say about the engines

Speed Utv has filed only fuel-injected engines: 72 certificate rows and no carburettors at all, so a jet kit is the wrong search for any of them.

The engine codes on Speed Utv's test vehicles —just one across the filings — are led by HS298MY-B. The code is stamped on the crankcase and is a better search term than the badge.

All 72 filings are 50-state certifications, so every one of these machines was certified for sale in California.

Rated power on the record is 168 kW (about 225 hp).

The vehicle builders named are Chongqing Huansong Science and Technology Industrial Co., Ltd. and Vietnam New Century Industrial Company Limited — 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.
