itll be hard to get a brand name because like most chinese minibikes,more than one company will produce the same design.but it looks like what we would refer to as a x bike. only i havent seen one with a 4 strke.isnt that a pirahna engine?might of been a transplant but looks too clean.lemme see if smeone in the minimoto world recognizes it.did you try pocket bike planet?btw....its no pocketbike!
