I wish some of the factories with current two strokes would embrace this. Maybe have Mike Brown show up with a Husky MX3 TC300.
the championship is official its just not a "world" champion, its EMX 300, check the MXGP calendar its mixed in with the events. Its definitely a "cheaper" way to go top level racing and another avenue for prospects to get noticed for MX1 and MX2 along with EMX125/250 series. http://fim-europe.com/index.php/about-fim-europe/fim-europe-calendar
