Video: Hamilton and Rossi's onboard hot laps at Valencia

Lewis Hamilton and Valentino Rossi swapped their racing machines at Valencia last week, and onboard footage of their respective hot lap has now been released.

Hamilton rode Rossi's 2019 Yamaha MotoGP YZR-M1 in what was his first experience onboard a genuine MotoGP machine.

The F1 star had arrived a day early at the Circuit Ricardo Toma to get acquainted with his beast and walk the track under the guidance of Italian motorcycle racer Franco Morbidelli.

Rossi was perhaps comparatively more at ease than Hamilton when he took to the track onboard the latter's former Mercedes W08, given the MotoGP legend's past F1 testing experience with Ferrari.

It was however Rossi's first run with a Grand Prix car from the hybrid era.
