It's interesting that on this site, they have the 200cc and 250cc bikes like yours listed as 'Jetmoto' and still have the 200cc and 229cc Bashans as well. Jetmoto and Roketa used to be manufactured by Shineray in the mid 2000's, but if your title states Bashan, that is probably who makes them now. Keep in mind, the EPA/DOT certification is much stricter now, and the older enduro bikes, like my Shineray manufactured Jetmoto 200, were technically dirt bikes, but many states allowed them to be registered for the street. The EPA and DOT cracked down and would not allow companies to introduce enduros with full street lighting if they were to be sold for off-road only use. What does your title say, and what does the manufacturer's plate say?
