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. "

As per tradition, the MotoGP World Championship will end with the Valencian Community Grand Prix, being held this year from November 15-17. Stage of the race weekend, Circuit Ricardo Tormo is located just outside Valencia and is named for the first world champion rider from Valencia who died prematurely in 1998. Each lap, the MotoGP riders turn to their brakes nine times, splitting fairly evenly the amount of left and right-handed turns: there are five left-handed corners and four right-handed. On one full lap, the MotoGP riders use their brakes for a total of 27 seconds, which is equivalent to 31% of the time needed to complete a lap. The average peak deceleration per lap is 1.16 G, the highest of the four Spanish tracks used in MotoGP. If the section composed of turns 4 and 5 were eliminated, this figure would definitely be higher.Summing up all of the force applied by a rider on the brake lever from the starting line to the checkered flag, the result comes in at about 1,020 kg (2,249 lbs). There are a good seven corners where the load reach at least 4 kg (8.8 lbs).
The hardest braking point on the Autodromo Nazionale Monza is in front of turn 11. The driver has to slow down around 109 km/h over just 72 meters. The calculated brake energy involved is 3,010 kW. The driver is subjected to 6.7 g, while he pushes with 211 kg onto the brake.
