# 2001 Grand Prix motorcycle racing season

The 2001 Grand Prix motorcycle racing season was the 53rd F.I.M. Road Racing World Championship season.

## Season summary

2001 was the end of the 500 cc era in Grand Prix motorcycle racing; in 2002 the premier class would be renamed MotoGP and dominated by 4-stroke 990 cc machines. However, 2001 was the beginning of another era, that of Valentino Rossi's run of championships in the top class. His learning year past him, he won 11 races in 2001, far outdistancing his nearest competitor, Max Biaggi. Rossi and Biaggi began the season with a controversial incident at Suzuka, where Biaggi seemed to have tried to push Rossi into the dirt at 150 mph and Rossi responded two laps later with an aggressive pass and an extended middle finger. Rossi would win that race and sew-up the championship with two rounds to go. It was the last season where an independent team rider won the rider championship title in the premier class, until 2024, which was won by Jorge Martín, riding for Pramac Racing.
The 500 cc Rookie of the Year award went to Shinya Nakano. At the 2001 Japanese motorcycle Grand Prix, Katja Poensgen became the first female competitor to qualify for a 250cc Grand Prix race.
As of 2023, it was the last year where a single constructor (Honda) won the championship in all three categories.
