He renewed his championship challenge in 2000. With Crivillé failing to regain his form, Roberts' main challenge came from Valentino Rossi, a rookie rider fresh from winning the 250cc title. This time, Roberts managed to find consistency by taking four wins and five podiums in 16 races. Roberts clinched his first title, two races before the end of the season, at the Rio Grand Prix after finishing 6th, although Rossi won the race. He became the first son of a former champion to also win the title. His victory also meant Suzuki broke Honda's six-year championship win streak.
