MotoGP – Preview Donington – Brembo forecasts

Below is the data provided by Brembo regarding the next British GP, the tenth round of the 2009 world championship which will be held for the last time on the Donington Park circuit. As usual, the 2008 data are compared with the 2009 forecasts. For example, it can be seen that the initial speed of curve 1 is higher (265 km/h compared to 255 in 2008); again in the same curve the braking distance is shorter in the 2009 forecast (197m against 200 in 2008) and the braking time is also slightly shorter in the 2009 forecast (3,8 sec. against 4,0 in 2008). The final speed of turn 3 (McLeans Corner) is higher than the 2009 forecast (120 km/h compared to 115 km/h in 2008) and in the same corner the braking distance is one meter in favor of the 2009 forecast. The maximum deceleration is equivalent to 1,2g. Below are all the data for the 7 corners of the next round of the 2009 world championship.
