They also discussed the importance of PETRONAS in their careers, with the fuel and lubricants proving to be a vital ingredient in the complicated recipe of success in racing.
"The PETRONAS brand means a lot to me because I can ride in the World Championship and we can have this opportunity," explained Ayumu. "It means everything to me."
Once the tour was completed, George, Niki, Ayumu and Adam returned to reception, where they got a close-up look at last year's Championship-winning W08.
The visit concluded with a photoshoot and some video filming outside the factory entrance.
