What the number itself says

Reading STBPX.140DBA left to right: S is the model-year letter for 2025, TBP is the three-character code the EPA assigned to Trail Blazer Powersports as certificate holder, X marks an off-road certification, .140 is the displacement in litres, so 140cc and DBA is Trail Blazer Powersports' own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.

The engine, as described on the certificate

The test vehicle Trail Blazer Powersports submitted for this family (model LK140) carried engine code 1P56FMJ. In the Chinese engine-model convention that reads as one cylinder, horizontal (flat) cylinder, with a nominal 56 mm bore, FMJ series.

The certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by carburettor. No catalytic converter is listed.

Rated power on the record is 6.8 kW (about 9 hp) at 7,500 rpm, driving through a 4-speed manual gearbox.

Filing history and where it was sold

Trail Blazer Powersports filed one certificate under this family, for model year 2025, sold as 49-state (not certified for sale in California).

Certified emission levels: CO 10, HC+NOx 1.0 g/km.

Other records carrying the same engine code

Trail Blazer Powersports certified an engine with this code under 2 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

  • RTBPX.140DBA (2024)
  • TTBPX.140DBA (2026)

Other certificate holders whose test vehicle carried the same engine code (10 of 15 shown):

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.

Models certified under STBPX.140DBA
