MotoGP, Michelin Tyre Tech Notes from Friday at Phillip Island:

As is very often the case at Phillip Island, it was cold and windy today. However, the track was dry for both MotoGP sessions, so the 3 front and 3 rear slicks were all tested.

Track temperatures were 20°C in the morning, rising to 28°C in the afternoon.
 
The front tyres performed well, the warm-up was good considering the conditions, and the difference between the 3 specifications was mostly in the stability and support they offered. The Soft was good for starting the morning session and for time attack. The Medium was more stable with good turn-in, while the Hard was very consistent and worked particularly well for the more aggressive riders.
 
The Soft rear offered very high levels of grip for 1 or 2 laps, but then the loss of potential was quite noticeable.
The Medium rear was more stable and consistent, but with less cornering grip and more sliding. The Hard rear was sliding in the cold and slightly green track conditions today, but more track time and higher track temperatures are likely to help it perform better as the weekend progresses.
