grand prix of bulgaria.

This weekend's Grand Prix of Bulgaria marks the mid point of the 2007 Motocross world championship season, in which Josh Coppins has been kept on his toes in MX1, while Antonio Cairoli has dominated MX2 class.

Bulgaria hosts round six of the 2006 Motocross World Championships this weekend, with Stefan Everts comfortably clear in the premier MX1 class - but with MX2 as unpredictable as ever.
