The Jerez tests saw the debut of a modern technology to allow communications between Race Direction and riders. As revealed by Motorsport, it is a one-way radio system that should improve safety. The Race Direction has pre-recorded messages available to warn the riders when, for example, an incident happens in one part of the circuit.
Fabio Quartararo, Aleix Espargarò and Jonas Folger were the three riders selected for testing, the Aprilia rider, however, wanted to keep the results strictly confidential: "I can't say absolutely anything".
The radio signal receiver is reported to be positioned in the leathers, while in the helmet there is a speaker, not an earpiece. Of course, the system is still in the prototype stage. First, they need to find the right technology and then gauge what the riders think about it, then further tests will be carried out during the year.
However, this is not the first time that such an experiment has been carried out in MotoGP, in 2020, it was Stefan Bradl (in a test at Misano) who tried a similar communication system.
