What the number itself says
Reading 7USRX.107ATV left to right: 7 is the model-year letter for 2007, USR is the three-character code the EPA assigned to USA Run Feng as certificate holder, X marks an off-road certification, .107 is the displacement in litres, so 107cc and ATV is USA Run Feng's own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.
