When was the last time a non-factory rider won a MotoGP race? Any MotoGP fan worth their salt will be able to give you year, track and rider: 2006, Estoril, Toni Elias.

Ask them why he won and they will give you all sorts of answers – Dani Pedrosa taking out Nicky Hayden in the early laps, Colin Edwards not being able to maintain his pace to the end of the race, Kenny Roberts Jr. misjudging the number of laps left in the race, or, as Valentino Rossi put it, because “Toni ride like the devil” – but none they can be sure of.

There is a less well-known explanation for Elias’ performance, though. Ahead of the Estoril race, Elias was given a set of the overnight special tires shipped in especially for Michelin factory riders.

In this case, Elias was handed a set of ‘Saturday night specials’ destined for Dani Pedrosa, but which Pedrosa had elected not to use, and so were going spare. Elias liked the same kind of soft carcass tire that Pedrosa was being offered, and went on to exploit the advantage it offered.

What does that have to do with Friday at Qatar? Two things. Firstly, it highlights exactly how important tires are in motorcycle racing. Tires dictate a huge amount of the performance of a motorcycle. They are the connection between the bike and the track, but that is a very full and complex function.

Tires determine how far a bike can be leaned, how much drive the bikes can get out of a corner, how well the power delivery of an engine transfers to the tarmac, how hard the bike can brake, they provide a certain amount of suspension, and they pass information about track surface, grip conditions and where the limits of braking and turning are for a motorcycle.

And that’s just the beginning. Tires are (quite literally) a black art. Their complexity cannot be underestimated.
