What the number itself says
Reading 7ZZLX.110AA1 left to right: 7 is the model-year letter for 2007, 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 AA1 is Zzl Motorsports' own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.
