This shot is at the Dunlop chicane at Le Mans. The bikes take a hard left then a hard right. As they transition between the two they lean one way then the other. If you are lucky enough to catch 3 or 4 bikes who are inches apart you can get the leading machine setting up for the right hander while the trailing one is still on the exit of the left. The overall effect is of a 'fan' of bikes if you can catch it.
