MotoGP, Saturday’s Michelin Tyre Tech Notes from Catalunya

Another hot day in Barcelona where the tyres were put to the test by the riders, but they held up well.
The lap times were very fast and the all-time circuit lap record was beaten twice by Aleix Espargaro - once in FP3 and once in Q2. His best time was 1’38.742
 
The track temperatures were 32° C in the morning, and climbed to 54°C in the afternoon sessions.
 
The track conditions were better today compared to yesterday due to more rubber having been laid by the bikes, although it was still slippery. At this moment the race tyre choices are not very clear because it will take the teams all night to closely analyse the data.
It is likely to be a difficult choice between:

Fronts - The Medium front, which works well on all bikes due to its good balance of grip and level of support/stability.
The Hard front could be an option for more demanding/aggressive riders/bikes. However, care will be needed on some left turns.

Rears - The Soft rear gives very good initial grip, but can have a tendency to move around which could lead to excessive wear and high temperatures.
The Medium rear is a good compromise between grip and consistency, and offers fast warm-up.
The Hard rear needs two laps to warm-up properly and then offers good stability and overall grip potential quite close to that offered by the Medium.
