Bayliss won three Superbike World Championship titles either side of a stint in MotoGP.

He capped off his second Superbike triumph in 2006 with his one and only MotoGP race win, taking the chequered flag as an injury substitute for the season finale.

His son Oli has followed in his footsteps and currently races in the British Supersport Championship.
