"I thought it was a really cool experience and it also helps when you have two guys who are enthusiastic about their sport and have a good mantra about it," smiled Busch. "I think Rossi is a really cool dude. We were just having fun, hanging out together. To me, I thought the experience was awesome. It's cool Monster Energy brought us together, it was a lot of fun. Just getting the feeling of asking him about his sport and him asking me about NASCAR a little bit. Just having the dialogue there was good."
"And as far as driving the car, I thought he did pretty good. He started out a little slow, which is fine, but every lap he picked it up a lot. He got to where he was running some competitive lap speeds – times that would put him in the top-15 in Nationwide Series practice. That's pretty good for a guy in his first start, who is just coming over and getting used to things and someone that is used to driving on two wheels."
Lin Jarvis, Managing Director of Yamaha Racing, was also present to witness the collision of two radically different forms of motor racing.
"For me it's really fascinating to come here to Charlotte, to the home of NASCAR – this is my first contact with NASCAR, ever - so it's something I really wanted to do at least one time. To be here with Joe Gibbs Racing and Kyle Busch, that's as good as it gets.
"To have Valentino mix it up here, experience the car, is a fascinating experience for him as well. I just saw Valentino when he came in off the track and even through that helmet, you could see that huge smile on his face. He's enjoying it and I think this is really great. Thanks to Monster Energy for making this possible."
As well as his record-breaking two-wheel grand prix career, Rossi has previously tested - and in some cases raced - F1, WRC, DTM and Sportscar machinery.
