What the number itself says

Reading TRAYX.120NC1 left to right: T is the model-year letter for 2026, RAY is the three-character code the EPA assigned to Raytech USA as certificate holder, X marks an off-road certification, .120 is the displacement in litres, so 120cc and NC1 is Raytech USA's own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.

Filing history and where it was sold

Raytech USA filed one certificate under this family, for model year 2026, sold as 49-state (not certified for sale in California).

The vehicle itself is recorded as built by Raytech (Qingdao) Power Science and Technology Co., Ltd. in China, while the engine came from Chongqing Hangdi Machinery Manufacturing Co., Ltd. Chassis parts and engine parts therefore have different origins.

Certified emission levels: CO 3.1, HC 0.5, HC+NOx 0.8 g/km.

Other records carrying the same engine code

Raytech USA certified an engine with this code under 10 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

• JRAYX.120CR1 (2018)
• KRAYX.120CR1 (2019)
• LRAYX.120NC1 (2020)

• SRAYX.120NC1 (2025)

Other certificate holders whose test vehicle carried the same engine code:

• Lil Pick Up Inc.HLLPX.120CRA2017 · same engine factory

A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
