Predicting how a MotoGP race will play out is hard. Scratch that, predicting how a MotoGP race will play out is downright impossible. We scour the sector and lap times, talk to as many riders as possible, try to make sense of what they tell us, and take our best guess based on all we have learned.

And inevitably, we get it wrong. Because there was something we missed, or because some random factor intervened, or because we didn’t pay enough attention to what the riders were telling us, or perhaps paid too much attention to it. Which is why you should probably take the following with a pinch of salt.

After qualifying and practice at Brno, we confidently predicted one of the best races of the year, with Jorge Lorenzo and Marc Márquez setting almost identical pace during free practice.

The chase lasted for five laps, before Lorenzo picked up his heels and disappeared, riding a perfect race to an unstoppable win, and killing any burgeoning excitement stone dead.

Silverstone looks like being very similar. There are two riders who are clearly a step ahead of the rest, and on the basis of practice times on Saturday, their pace is very similar indeed.

Though you wouldn’t say that just based on the headline numbers: in FP3, Jorge Lorenzo destroyed the rest of the field, beating Márquez by nearly half a second.

In the afternoon, during FP4, Márquez returned the favor, laying down a withering pace to put over eight tenths on everyone else, and posting a string of ten laps, the slowest of which was faster than fastest lap set by any other rider on the field.

The difference between Lorenzo’s FP3 lap and Márquez’ FP4 lap? Just 0.062 seconds, in Lorenzo’s favor.

Tires are what made the difference. Lorenzo put a brand new tire on for the last two laps of FP3, and obliterated the rest of the field. Márquez put a brand new medium tire in FP4, and blew the field away, then slapped in a new hard tire, and was fast with that too.

In FP3, Márquez was working on getting the best out of old tires, in FP4, Lorenzo was doing the same, as well as trying out a setup change that simply did not work.

Two riders, similar pace on new tires, both much faster than the rest. Who will come out on top? At this point in time, it is impossible to say. What it will come down to is who manages tires the best.
