Qatar's floodlit Losail circuit will host next season's opening MotoGP on March 6, according to the provisional calendar released by promoters Dorna on Friday.

In the calendar yet to be rubber stamped by the International Motorcycling Federation, the pre-season 'shakedown' for factory test riders and rookies will be held in Sepang, Malaysia, from January 31 to February 2.

Sepang will again be the venue for pre-season testing open to all riders on February 5-6, with Indonesia's new Mandalika street circuit hosting another round of practice on February 11-13.
