Dirt bikes have their origin in Britain, where crazy people took their newfangled motorcycles and started racing them around fields in scrambling competitions. There were no specialised bikes, everyone was running "road bikes", so the first trick was probably a powerslide
the first dirt-bike ever made was a honda. There were bike manufatures in Europe that were making dirt type bikes before Honda was even a company.
