What the number itself says

Reading SJYMC.169DP1 left to right: S is the model-year letter for 2025, JYM is the three-character code the EPA assigned to Jymoto Enterprises as certificate holder, C marks a highway (street-legal) certification, .169 is the displacement in litres, so 169cc and DP1 is Jymoto Enterprises' 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

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.
