What the USA Motortoys filings say about the engines

USA Motortoys has filed only fuel-injected engines: 6 certificate rows and no carburettors at all, so a jet kit is the wrong search for any of them.

The engine codes on USA Motortoys' test vehicles —2 distinct across the filings — are led by Z194YMQ and Z288MW. The code is stamped on the crankcase and is a better search term than the badge.

All 6 filings are 50-state certifications, so every one of these machines was certified for sale in California.

Rated power across the range runs from 38 kW to 71 kW (about 51 to 95 hp).

The vehicle builder named on every row is TIBET NEW SUMMIT 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.
