What the number itself says

Reading SEGLX.249LYA left to right: S is the model-year letter for 2025, EGL is the three-character code the EPA assigned to Egl Motor as certificate holder, X marks an off-road certification, .249 is the displacement in litres, so 249cc and LYA is Egl Motor's 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 Egl Motor submitted for this family (model MAX-7) carried engine code 172FMM. In the Chinese engine-model convention that reads as one cylinder with a nominal 72 mm bore, FMM series. Against the certified 249cc that implies a stroke of roughly 61 mm — a sanity check for a piston or cylinder listing, not a published figure.

The certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by carburettor, run by an ignition control module (CDI-type ignition). There is a catalytic converter in the exhaust, recorded as "TWC, single bed, open loop". The head carries a pulse secondary-air (PAIR) valve.

Rated power on the record is 14 kW (about 19 hp) at 8,000 rpm, driving through a 5-speed manual gearbox.

Filing history and where it was sold

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

Certified emission levels: CO 7, HC+NOx 0.6 g/km.

Other records carrying the same engine code

Egl Motor certified an engine with this code under 9 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

• HEGLX.249LYA (2017)
• JEGLX.249LYA (2018)
• KEGLX.249LYA (2019)

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

• Rato Usa, LLCARATC0.23N1R2010 · different 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.
