What the number itself says

Reading 8KNGX.300ACA left to right: 8 is the model-year letter for 2008, KNG is the three-character code the EPA assigned to Kangchao Group (Usa) as certificate holder, X marks an off-road certification, .300 is the displacement in litres, so 300cc and ACA is Kangchao Group (Usa)'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 Kangchao Group (Usa) submitted for this family (model BS300S-10) carried engine code BAS274L.

Filing history and where it was sold

Kangchao Group (Usa) filed one certificate under this family, for model year 2008, sold as 50-state, California included.

The vehicle itself is recorded as built by the same company, Chongqing Astronautic Bashan Motorcycle Manufacturing Co., Ltd. in China — engine and chassis from one source.

Certified emission levels: CO 5.7, HC 0.55, NOx 0.30 g/km.

Other records carrying the same engine code

Kangchao Group (Usa) certified an engine with this code under 4 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

• 8KNGX.250AMA (2008)
• 8KNGX.250AML (2008)
• 8KNGX.300AML (2008)
• 9KNGX.250AML (2009)

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.

Every model designation the importer listed on this certificate. If your machine's model name appears here, this is the right record — even if the name on the bodywork is slightly different.
