What the number itself says
Reading 7KNXC.150SA1 left to right: 7 is the model-year letter for 2007, KNX is the three-character code the EPA assigned to Konced Motorcycle Co., (Usa) as certificate holder, C marks a highway (street-legal) certification, .150 is the displacement in litres, so 150cc and SA1 is Konced Motorcycle Co., (Usa)'s own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.
