WorldSBK/SSP races at Phillip Island will feature mandatory pit stops

WorldSBK 2024
Round One – Phillip Island

Based on the information gathered following the WorldSBK and WorldSSP tests at Phillip Island earlier this week and a report from the Fédération Internationale de Motocyclisme (FIM) Technical Director, the Race Direction together with the Phillip Island Grand Prix Circuit and Dorna WSBK Organization (DWO) have decided that to ensure the safety of all participants, rear tyres shouldn’t be used for more than 11 laps for the WorldSBK class and 10 laps for the WorldSSP class.

Thus the races will take place under flag-to-flag rules, with a mandatory entry to the pits to change tyres for all bikes.

Additionally, the race distance for the WorldSBK Race 1 and 2 has been reduced to 20 laps and two extra sets of tyres have been allocated for each rider in both classes.

“The circuit has performed admirably with the new asphalt. While rubber is gradually laid down track conditions evolve, which present some challenges. Since the tyres were shipped out in late November to arrive for this opening round, there wasn’t enough time to develop specific tyres tailored to the current asphalt conditions. We have carefully assessed the situation, considering the early track activity following the asphalt’s being laid out and the two days of testing we conducted earlier this week. While conditions have certainly improved, they may not have improved enough, especially considering the challenging, fast-paced nature of this circuit layout. In such circumstances, we, in collaboration with Race Direction, the FIM and the Phillip Island GP Circuit, must opt for the safest option, which is of paramount importance.”

“We know this track very well, nevertheless every year it’s a whole other story because at Phillip Island the variables that can influence tyre behaviour are many and often unpredictable. This year the most critical element is represented by the new asphalt which has almost completely reset the references we had. I remind everyone that the tyres for this race were shipped from Europe at the end of November while the resurfacing of the circuit was completed only a few weeks ago. Therefore, in the absence of data on which to base ourselves, we thought it appropriate to rely on the racing solutions used successfully in the last two seasons.

“We have seen in the tests that the asphalt offers a lot of grip, to the advantage of the flying lap time, but on the other hand it is very aggressive with the tyres, especially at high temperatures, causing unusual peaks in tread compound temperature on the left side with consequent tyre degradation: we detected up to 160 degrees Celsius in pit lane which we estimate could reach operative peaks of more than 200 degrees. Considering this evidence, in agreement with Dorna, FIM and Race Direction, we have decided that for the races of both classes it will be mandatory to make a pit stop to change tyres. It was a difficult decision to take, also because, as always happens in these cases, some teams would have wanted to try racing over the full distance. However, Pirelli believes that the safety of the riders must be the absolute priority in such circumstances.”

The domestic Australian Superbike support races will stay at their scheduled 12 lap distance.
