Every day that sees MotoGP motorcycles circulating in earnest is an interesting day, but some are more interesting than others. Friday at Misano was one of those days which last, throwing up surprises and shattering preconceptions.

We found out that we need to throw overboard a lot of the things we thought about the current state of the MotoGP championship.

First, to the things that were not a surprise. That Yamahas should top both sessions of free practice, and establish themselves as favorites for the race was entirely to be expected.

That Valentino Rossi should impress is no surprise either: Misano is his home race, and a win here is his best chance of getting back into the championship. Jorge Lorenzo finding his feet again, and laying down a withering pace raised one or two eyebrows among those who had written him off.

But the real shocker was Pol Espargaro topping the second session of free practice, and ending the day faster.

Has Yamaha smuggled a few go-faster bits into the Monster Tech 3 Yamaha garage? The answer to that question is quite simply no. Espargaro’s pace has a very simple explanation: the Spaniard has been strong throughout this season, the switch to the Michelins playing to his strengths.

“This is a track where I am fast,” Espargaro told us. “If we add here the new tires which are really grippy on the rear and quite good performance on the front, I feel like I can ride in my style, aggressive and opening the throttle really early with full lean angle. I feel really comfortable riding the bike.”

Plus, of course, the small matter of time gained by using another fast rider as a target. “For sure, I was behind Márquez, and it helped me two tenths more or less.” Taking away two tenths of a second would put him third rather than first, but as he was second fastest in the morning, Espargaro’s time in FP2 was no fluke.
