At Tech3, Pol Espargaro is back as Maverick Vinales continues to recover from his injury troubles.
Johann Zarco is back in action this morning over 100 days after that horrifying crash he had at Barcelona.
I think I speak for us all when I say it is very good to see the smiling Frenchman back on his LCR Honda.

It's already pretty hot out there for this time of the morning. Air temp is up at 21C.
