The day after a race is simultaneously the best and the worst time to go testing. The best time, because the track is in great condition, having already seen three days of action. Riders are all fully up to speed, with both the track and with their riding.
It is also the worst time, because riders and teams are exhausted after the intensity of a race weekend, having given their all to try to win at the track. Testing after a race weekend is probably the least worst solution.
The Monday test after Jerez saw this point very well illustrated. With temperatures very similar to race day, the MotoGP teams – all bar the factory Ducati men, who were headed to Mugello for a test there on the 11th and 12th May – found a track in almost identical condition to the race, in which they could test things they didn’t have time to over the weekend, to try to find where they want wrong.
