Shocked faces
However, there was time for fun as earlier in the day, Zarco, Fabio Quartararo (MB Conveyors - Speed Up Racing) and Jules Danilo (Nashi Argan SAG Team) went undercover to welcome fans arriving to the track - with a few shocked faces and double takes as the three went incognito.
Then, the International Handy Racers were once again given the honour of kicking the GP weekend into gear as they took to the track for a couple of laps.
Full focus
Then it was full focus ahead for the French GP, and Marquez was the first man to speak first in the press conference. The Spaniard had crashed out at Le Mans last season, and he explained the big step forward Honda has taken since a more difficult 2017 weekend.
"Last year our weak point was acceleration. We were losing out too much and trying to recover in the corners - but this year we've improved that a lot. I hope the general weekend will be different this year."
Extra motivation
One rider arrives with a lot of extra motivation - Zarco, racing on home turf and second in the title fight. The Frenchman was also on the podium last season, for the first time in the premier class.
It's not more difficult," Zarco smiled and shrugged it off when asked about the pressure of his home round.
Great record
Nine-time world champion Valentino Rossi spoke of both his and the M1's great record at Le Mans.
"We arrive from a difficult moment because I'm not very fast. We worked on small details in Jerez, and Mugello. I think our level is similar to Jerez but usually the M1 works well at this track. In the last years here I was always strong, but we need to understand this year how our level is compared to that of our opponents."
