Lewis Hamilton's performance in his maiden test outing on a MotoGP bike was "brilliant" according to nine-time world champion Valentino Ross🐭i following their ride swaไp in Valencia on Monday.

Six-time Formula 1 world champion Hamilton linked up with Rossi through mutual spons🏅or Monster to sample a MotoGP bike for the first time at the Circuit Ricardo Tormo on Monday, jumping on the 2019-spec Yamaha MotoGP YZR-M1 bike.

ꦫIt added to Hamilton's growing experience on two wheels, having completed a test on a Yamaha Superbike at Jerez in December 2018 - only this time around, he had Rossi alongside him on-track through the test.

“It was soඣ cool to be out on track and see Valentino ahead of me on the same bike," said Hamilto🤪n, who won high praise from The Doctor.

"Technically, Valencia is a hard track and today was windy so at one point✱ I thought it would be difficult💧 for Lewis to continue," said Rossi.

"But he was brilliant on the bike and his position on the M1 was great. I think he had loads🐈 of fun which is the main thing."

Hamilton was also on hand to see Rossi complete his first♔ F1 test in almost a decade, as the Italian drove the 2017 F1 championship-winning Mercedes W08 car.

“It’s so awesome to see a legend like Valentino in the car. I’m excited for him, for discovering the car ♌for🥃 the first time - it reminds me of my first time in a F1 car," Hamilton said.

"When you see all the team around you, it’s just a different animalꦕ.”
