Hardly anybody cares a rats ass about Zarco any more.
There's at least 8 fast riders in Moto 2 and Moto3 that will grab that FULL FACTORY KTM ride in a second.
The other factories know if Zarco isn't happy, nobody is going to be happy, including sponsors.
Any rides Zarco may be looking at are being looked at by those other 7 riders, who are 7 years younger and have no history of histrionics.
If he's lucky, he might get a test rider gig. With a gag order written into his contract.
