It is a common enough sight in Grand Prix racing: slower riders cruising around at the edge of the track, waiting for a faster rider to come by so they can get a tow. It is especially common at the Motorland Aragon circuit. With its massive back straight of nearly a kilometer in length, a decent slipstream can be worth an awful lot.
It is less common to see slower riders cruising for a tow in MotoGP. In Moto3, sure: with horsepower at a premium, cutting down on drag equates to free speed. In Moto2 as well, as the fact that the bikes all produce exactly the same horsepower means that riders have to find an advantage anywhere they can. But MotoGP? A lack of horsepower is not really a problem in the premier class. The bigger problem is usually transferring it to the tarmac to generate drive, and translate that power to speed.
But Aragon is different. Sure, tucking in behind another bike can give you extra speed using their draft, but above all, using another rider as a target makes you that little bit faster. "MotoGP is so close now that if you can follow someone, get a bit of a tow, that's obviously going to improve your time," Bradley Smith explained on Saturday afternoon. "We don't see it very often in MotoGP, to be honest, as much as it was today, but it shows how important it is here in Aragon."
