Which motorcycle carried Valentino Rossi to the 2004 MotoGP World Championship?

The story behind the answer

The Yamaha YZR-M1 carried Valentino Rossi to the 2004 MotoGP World Championship.

Rossi won the 2004 premier-class title in his first season with Yamaha’s factory MotoGP team. The YZR-M1 was Yamaha’s four-stroke prototype developed after MotoGP replaced the 500cc category in 2002.

His move from Honda to Yamaha made the achievement especially notable. Rossi and the YZR-M1 won the opening round at Welkom, South Africa, and established a successful partnership that reshaped Yamaha’s modern MotoGP history.

The YZR-M1 is sometimes confused with Honda’s RC211V, which Rossi rode to the 2002 and 2003 premier-class championships. The 2004 title was Yamaha’s achievement.
