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.
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).
At the Malaysian GP the MotoGPs use the brakes for 35 seconds per lapFor the fifth year in a row, the penultimate round of the MotoGP World Championship will be staged at the Sepang International Circuit. The Malaysian GP is held from 2 to 4 November on the circuit designed by Hermann Tilke and inaugurated in March 1999.Located 85 km from Kuala Lumpur, within a 260-hectare palm oil plantation, it is the second longest track in the World after Silverstone and one of the toughest for the MotoGP braking systems.Formula 1 also competed here but the brakes of the cars were less stressed than those of the bikes. For the MotoGP, the numerous braking points, the high percentage of time spent braking and the tropical climate make the handling of temperatures quite critical, both for the brakes and for the pilots: in 2015, during the race, the air temperature was of 35 degrees and that of the asphalt of 47 degrees.In 2016, however, the rain was protagonist in FP2, FP4, Q1, Q2 and even in the race: several pilots tried the Brembo carbon discs to overcome the problems of variability of the weather and intermittent rain. That experiment proved to be decisive for the victories in 2017, under the rain, by Marc Marquez in Misano Adriatico and Andrea Dovizioso in Motegi with carbon discs.According to Brembo engineers who assist 100 percent of the 2018 MotoGP riders, the Sepang International Circuit falls into the category of highly demanding braking circuits. On a scale from 1 to 5, a difficulty index of 5 was deserved, a value also recorded by Motegi, Spielberg and Barcelona.
The third round of Asian-oceanic poker is the Australian GP scheduled from 26 to 28 October in Phillip Island (Australia) and is valid as the 17th round of the MotoGP World Championship. Inaugurated in December 1956, the track hosts the 500-MotoGP since 1989 and the Superbike World Championship since 1990.Located on the island of the same name 140 km from Melbourne, it is the closest circuit to the South Pole of the entire championship. In the last three editions, its 38 degrees of latitude have translated into rather harsh temperatures: in 2016 during the race the air temperature reached a maximum of 13 degrees and last year did not exceed 16 degrees.In order to keep the initial temperature of the brakes adequate, MotoGPs often use carbon covers, the same ones used in other circuits in case of rain. In the event of rainfall the pilots could instead use steel discs but at Motegi, last year the first 9 at the finish showed that it is possible to run with rain even with Brembo carbon discs without suffering but rather taking great benefits.According to Brembo engineers who assist 100 percent of the 2018 MotoGP riders, the Phillip Island Grand Prix Circuit falls into the category of poorly demanding brake circuits. On a scale of 1 to 5, a difficulty index of 1 was deserved, a value not recorded by any of the other 18 tracks. The same score also obtained for Superbike.
"Two weeks after Formula 1, MotoGP also arrives in Japan for the 16th round of the World Championship, scheduled from 19th to 21st October at Twin Ring Motegi. Built by Honda in 1997, it is located on the hills surrounding the town of Motegi, on Honshū Island, the largest in the country. The name Twin Ring derives from the union of the English terms Twin and German Ring and serves to indicate the presence on this area of two tracks: an oval and a road circuit that intersect between the curves 5-6 and 11-12. Of course, the MotoGP uses the road circuit that is characterized by a few fast corners and many lenses, interspersed with straights of medium length: there are even 7 curves faced by the bikes at less than 100 km / h. Just the abundance of second gear corners makes it since its first use in the World Championship, in 1999, one of the most challenging for the brakes complicit the difficulty of cooling the discs between a detached and the other."
