What did we learn from the first day of practice at Brno? Not much, but that in itself is valuable. The COVID-19 pandemic meant that the Automotodrom Brno circuit has not seen much action, so there is very little rubber on the track. The circuit has always been fairly low grip, but it is much worse now than it has ever been. It needs rubber down on it before any conclusions can be drawn.
That makes figuring out what is going on rather tricky. The track is changing session to session, as bikes deposit a thin smear of Dunlop and Michelin rubber on the surface of the track and in the crevices between the grit particles used in the aggregate. That leads to big changes in grip levels: Fabio Quartararo's fastest time in FP2 was over eight tenths faster than the best lap set by Takaaki Nakagami in the morning session. Quartararo's best time from Friday was nearly three quarters of a second slower than the best time at the end of the first day in 2019.
With the times so far off the pace – Quartararo's time is two whole seconds off Marc Márquez' outright lap record, and half a second slower than the race lap record – and grip still changing, conditions were just to inscrutable to draw any conclusions from, or at least any conclusions which might last beyond Saturday morning. Trying to work out which tire will work best was almost possible on Friday. There are still too many unknowns.
Bump and grind
