At the grand finale in Valencia, the MotoGP riders have to apply a great deal of force on the brake lever

11/6/2017

At the Valencia GP, watch out for the Martinez and Herreros corners

As per tradition, the MotoGP World Championship will end with the Valencian Community Grand Prix, being held this year from November 10-12.

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.

Inaugurated on September 19, 1999, it is distinguished by the length of the circuit which is just 2,489 miles (only Sachsenring is shorter), meaning the 65,000 spectators in the stands can keep the entire track within eyeshot.

The bikes travel counter-clockwise and have to face lots of corners, both left-handed (9) and right-handed (5).

Except for the long front straight, the track is made up of tight, technical corners where low gears are often used. It's no wonder that the average lap speed is the lowest in the entire championship: The record lap time is 100.2 mph, nothing compared to the 116.1 mph on Red Bull Ring.

According to the Brembo technicians who assist 100% of the riders in the 2017 World Championship, Circuit Ricardo Tormo earned a 3 on the difficulty index, the lowest score of the four Spanish tracks in the World Championship.

 

 

 
 

The demand on the brakes during the GP

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 30% of the time needed to complete a session.

The average peak deceleration per lap is 1.14 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 3,109 lbs.

There are a good seven corners where the load goes over 11 lbs.


 

The most demanding braking sections

Of the 9 braking sections on the circuit, only one is considered very demanding on the brakes, while five are of medium difficulty and three are light.

The most challenging corner is the first, which is named for Jorge “Aspar” Martinez, four-time World Champion.

The MotoGP bikes enter the area at 201 mph and brake for 4 seconds in 266 yards to decelerate to 84.5 mph.

The riders put 13 lbs of pressure on the brake lever and are subjected to 1.5 G in deceleration. The pressure of the Brembo HTC 64T brake fluid reaches 12.4 bar on turn 12, which is named for Champi Herreros, world champion in the 80cc class in 1989. The MotoGP bikes drop 59 mph to go from 136 mph to 77 mph in a mere 2.3 seconds and 119 yards.

To do so, they have to apply a load of 16 lbs on the brake lever.

Longer but less intense is braking on the second corner, which is named for Mick Doohan: 172 yards and 4 seconds of braking, with a deceleration of 1.3 G and a 13-pound load on the lever.

This is one of the five turns on the track that are taken at less than 62 mph.

Another one of these is turn 8 with its 196 yards of braking space traveled in 4.2 seconds.

 

 

Brembo performance



Motorcycles with Brembo brakes have won all the last 18 Valencian Community Grand Prix races contested so far in the premium class. The first to take the victory was Regis Laconi with Yamaha in 1999.

Of the last five races, Spanish riders won every time and at three of these, Jorge Lorenzo stood on the top podium, just like he did in 2010. Valentino Rossi hasn't won on this track since long ago 2004.
