For the first time Bulgaria will host the MX GP opener. The Sevlievo track is one of the best of the year with its massive up- and downhill sections and lots of jumps.
KTM is the team to look at with the two world champions under its tent. While Michael Musquin is used to the orange machine it will be interesting to see Tony Cairoli for the first time racing an orange bike. He will ride the all new 350cc machine.
