Pit stops will be enforced at Phillip Island on Sunday.

Tomorrow’s Tissot Australian Motorcycle Grand Prix will feature the first ‘flag-to-flag’ type MotoGP race in dry conditions due to safety reasons.

Race direction has announced that they “have been notified by Bridgestone that they are unable to guarantee safety of their rear slick tyres beyond 14 laps”.

The race will officially be reduced from 26 to 27 laps, with every rider required to enter the pits and change to their second machine with fresh tyres at least once during the race.

No rider is permitted to make more than 14 laps on any one slick rear tyre. This means that a bike/tyre change before lap 12 will require a second bike/tyre change to finish the race.

Factory and Satellite riders will be required to use the B51DR hard option tyre, with CRT runners to use the B50DR combination.

As a result, the pit lane speed limit zone will be extended both on entry and exit, and the exit route to rejoin the track will be marked by a white line in the runoff area. Crossing this line whilst rejoining the track from pit lane will result in a penalty.

Earlier, it was confirmed that the Moto2 race would be slashed from 25 to 13 laps due to issues with the Dunlop control tyre.
