MotoGP, Alpinestars responds to Fabio Quartararo's open suit: a constraint never seen before

The open suits of pilots in the middle of a race or after violent falls have entered a dangerous series putting them in danger. This year, Jorge Martin rode during the Austrian Grand Prix with the zipper ajar, at Silverstone, Aleix Espargaró saw his suit open after his heavy fall. In Aragon, Fabio Quartararo's leather also opened, causing burns to the torso for the Frenchman in distress. Alpinestars has analyzed this fact. And that’s his expertise.

The analysis ofAlpinestars is thus online on the site Moto.it : " after colliding with another motorcycle exiting turn 3, Fabio tilted towards the front of his Yamaha causing the airbag to inflate correctly before the first impact with the ground. The fall forward, beyond the bike, was complicated by the fact that after Fabio hit the ground and slid onto his back (hinge intact at this point), he then received a significant secondary shock to the chest from the front wheel of his motorcycle ».

« Our analysis led us to conclude that the airbag inflated at the first impact significantly stretched the suit. Due to the abrasion resistance between the back of the suit and the asphalt when falling, a tensile stress factor was generated ».

Fabio Quartararo was hit in the chest by the front wheel of his motorcycle 

« When the front wheel of the motorcycle came into contact with Fabio's chest, it grabbed the leather of the suit, stressing the zipper's tightness beyond any level recorded in the thousands of drops we've analyzed so far, with the consequent failure of the teeth of the same closure. This conclusion follows from the fact that all elements of the suit are intact, including the seams, including those that attach the zipper to the suit'.

« Alpinestars wants to clarify that, although this seems to be an extraordinary circumstance, work is already underway on solutions that do not allow the event to repeat itself ».
