Which of those machines are actually comparable
A shared factory alone is a weak signal — Zhejiang Jiajue builds engines across 49–248cc. Grouping by engine size narrows it to machines genuinely worth comparing.
VIN prefixes assigned to Zhejiang Jiajue
If your frame number starts with one of these three characters, NHTSA has it recorded against this manufacturer. Check the first three characters of the VIN stamped on the frame or shown on the VIN plate.
| VIN starts with | Company as NHTSA records it | Vehicle type |
|---|---|---|
| LLP | ZHEJIANG JIAJUE MOTORCYCLE MANUFACTURING CO., LTD. | Motorcycle |
A VIN prefix identifies the company that registered the code, which is not always the company that built your engine — importers sometimes register their own. Treat it as corroboration for the emission label, not a replacement for it.
