Mugello MotoGP: Alpinestars data on Marquez 200mph fall

3 June 2013

Alpinestars have released the following data, recorded from the Tech Air (airbag) system of Marc Marquez during his huge Friday practice fall at the Italian MotoGP.

Note that the maximum of 25g is the highest the sensors can record, rather than the peak reached in the accident, which occurred when Marquez got out of shape under braking at the end of the fastest straight on the MotoGP calendar:

Speed at time of loss of control: 337.9 km/h (209.9mph).
First impact with ground: 0.080 seconds after crash detection.
First impact with ground: 0.030 seconds after full airbag inflation (airbags inflated in 0.050 seconds).
Maximum (recorded) energy in crash: 25g (the Tech Air system accelerometers maximum energy recording capability).
Duration of significant data during the accident: 4.250 seconds.

Amazingly, race-winning rookie Marquez - who 'jumped' from his Repsol Honda as it veered towards a trackside wall - escaped with relatively minor chin (pictured) and shoulder injuries and was able to compete in the remainder of the weekend.

However his efforts went unrewarded: Marquez fell from second place in the Mugello race, with just three laps to go.
