However, because of the heat and the big braking, this is also one of the most challenging tracks all year for thedrivers' physiques and for the brakes, which are heavily stressed throughout the course.
For the braking system, in fact, the most difficult corners are in order the first, tenth and fourth. The first one is definitely scary: you come down the straight at a speed of 342 kmh and in a braking distance of 275 meters, the MotoGP drops to 99 kmh in 5.6 seconds.
Almost all other braking is firm and close.
The Catalan circuit therefore represents a challenge for Brembo, a leading company in braking systems. In fact ona scale of 1 to 6 it earned a difficulty rating of 5, identical to Sepang International Circuit and lower only than the Red Bull Ring, Twin Ring Motegi and Chang International Circuit tracks.
