"There's not a lot of flow to the layout. I'd say the last little bit looks like something they threw together just to finish the lap, like they were in a hurry to get it done. You need the bike to be stable on the brakes, for sure, you definitely need something for some hard braking. You also need good acceleration from the engine, something that's smooth and controllable off the bottom.
"The weather can change a lot too, so your tyre picks on Thursday are pretty crucial. The track can generate some pretty high temperatures in the tyres and you need good traction accelerating out of all the hairpins because the asphalt at Le Mans can be quite slippery," he added.
