Following the event in South America, MotoGP is moving onto North America for the 3rd race of the 2018 World Championship scheduled for April 20 to 22 at the Circuit of the Americas (Austin, Texas). The track was designed by German architect Hermann Tilke and is one of the few circuits in the world to host both the MotoGP World Championship and Formula 1: the single-seaters register a lap time half a second lower than that of the motorcycles. Some stretches on the track were inspired by famous corners on historic circuits. The Texan circuit stands out for the intimidating incline on the straightaway leading to the first left-hand turn. In all, there is a difference of 133 feet between the lowest and highest points on the track, which makes it easy to imagine what might happen if the riders make a mistake in braking on the downhill stretch.
"Johann Zarco had a brilliant debut into this season. Next up is the sold-out fifth race of the 2018 World Championship at Le Mans scheduled for May 18-20. The French circuit was built in 1965 around the 24 Hour of Le Mans track, with which it shares a third of the track. Named for Ettore Bugatti, the circuit hosted the 500cc class of the World Championship for the first time in 1969, but it has been a permanent site of the French GP only since 2000. The track is 4,2 km long and in October 2016 it was completely repaved for the first time in 12 years. The new pavement guarantee better grip, which would enable the bikes to discharge more braking torque than in previous years. The straightaway at the arrival is only 674 meters long but since there are lots of other straightaways, the riders can easily cool down their Brembo carbon discs. To ward off the opposite risk, many of the riders will probably adopt brake discs with a low braking surface. "
Everything you need to know about the demands on the braking systems mounted on the bikes ridden by Vinales, Rossi, Marquez and Dovizioso. With the 3 non-European rounds out of the way, MotoGP heads to Spain for the 4th round of the 2017 season, scheduled to take place from 4 to 6 May on the Circuito de Jerez. Opened on 8 December 1985, this track has hosted the premier class since 1987. Oddly enough, however, in 1988 the race was labeled the Portuguese GP because the Spanish GP was held in Jarama. On every lap, the riders will have to use the brakes 11 times for a total of 33 seconds. In absolute terms, that is not excessively high, especially if compared with the 38 seconds per lap at Austin and the 37 at Losail. However, on these two tracks, the lap records range from 1’55’’ to 2’05’’, whereas at Jerez lap times are 1’39’’ and that gives the Spanish track the highest percentage in the championship of time spent braking: 33 percent.

The hardest braking point on the Silverstone Circuit is in front of turn 3. The driver has to slow down around 178 km/h over just 107 meters. The calculated brake energy involved is 1,900 kW. The driver is subjected to 4.7 g, while he pushes with 140 kg onto the brake.
