What the number itself says
Reading 6ZZLX.110ZLA left to right: 6 is the model-year letter for 2006, ZZL is the three-character code the EPA assigned to Zzl Motorsports as certificate holder, X marks an off-road certification, .110 is the displacement in litres, so 110cc and ZLA is Zzl Motorsports' 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

Rated power on the record is 5.2 kW (about 7 hp) at 7,500 rpm.

Filing history and where it was sold
Zzl Motorsports filed one certificate under this family, for model year 2006, sold as 50-state, California included.
The vehicle itself is recorded as built by Zhejiang Zili Industry and Trade Co. Ltd. in China, while the engine came from Chongqing Loncin. Chassis parts and engine parts therefore have different origins.
Certified emission levels: CO 11, HC+NOx 0.4 g/km.
