## Season summary
### MotoGP class

The season marked the start of a new era in the premier class with the arrival of 990cc four-stroke bikes. Four factory teams, Repsol Honda, Marlboro Yamaha, Suzuki and Aprilia, raced with the new four-stroke bikes while all the satellite teams raced with the 500cc two-stroke bike. The season also marked the return of Dunlop and the entry of Bridgestone to the premier class. Dunlop supplied the tyres for Suzuki, Aprilia, Yamaha WCM and Pramac Honda. Bridgestone supplied the tyres for Team Roberts and Kanemoto Racing. Michelin supplied the tyres for the remaining six teams. However, after only two races, Suzuki switched back to Michelin tyres for the remainder of the season.
Valentino Rossi, riding the four-stroke Honda RC211V bike, won the first race of the season at Suzuka under wet conditions. Suzuki's test rider Akira Ryō, who raced as a wildcard entry, and Yamaha's Carlos Checa completed the all four-stroke podium. Rossi's teammate, Tohru Ukawa, won the second race before Rossi went on to dominate the championship by winning seven consecutive races. Max Biaggi handed the four-stroke Yamaha YZR-M1 its first win in the Czech Republic Grand Prix at Brno, while Rossi had to retire due to tyre problems. In that race, Honda also expanded their four-stroke presence by providing the RC211V bike for Honda Gresini rider Daijiro Kato. Rossi then won two consecutive races in Portugal and Brazil, clinching the world championship in the latter.
In the Pacific Grand Prix, Honda Pons rider Alex Barros won his first race riding the RC211V bike. In that race, Kawasaki returned to the world championship after 20 years absence. Kawasaki, with their four-stroke Ninja ZX-RR, raced as wildcards in the last four races of the season as a preparation before entering the championship full-time in the following season. In the following race at Sepang, Yamaha expanded their four-stroke presence by providing the YZR-M1 bikes to Tech 3 pair Olivier Jacque and Shinya Nakano. Another Yamaha rider, Norifumi Abe, raced the fifth YZR-M1 on the grid for the last two races of the season.
Rossi ended the season with 355 points from 11 wins and four second places. Biaggi finished second to Rossi with 215 points and two race wins. Ukawa and Barros completed the top four with 209 and 204 points respectively. Previous year's 250cc champion Daijiro Kato finished in seventh position with two podium finishes and was named as the Rookie of the Year. All races were won by the four-stroke bikes, while the two-strokes only managed to record five podiums finishes. Honda won the constructors championship with 390 points and 14 wins, followed by Yamaha who won the other two races. Repsol Honda team won the teams championship by winning 12 races and scoring 564 points from Rossi and Ukawa. Marlboro Yamaha and Honda Pons who won two races each was second and third respectively.

### 250cc class

The 250cc class was certain to have a new champion as previous year's champion Daijiro Kato and 1993 champion Tetsuya Harada, who finished second to Kato last year, both moved up to the MotoGP class. Only three riders remained from previous year's top six: Marco Melandri, Roberto Rolfo and Fonsi Nieto. Melandri was the only rider in the 250cc class who has previously won a 250cc race; he won his first and only race in the 2001 German Grand Prix. The 250cc entry list also included three former 125cc World Champion: Haruchika Aoki, Roberto Locatelli and Emilio Alzamora.
The season started with a wet race at Suzuka which was won by Japanese wildcard rider Osamu Miyazaki, who was riding for Daytona Yamaha team. Honda's wildcard rider Daisaku Sakai and Aprilia's Randy de Puniet completed the podium. In the following race at Welkom, Aprilia's Marco Melandri took his second career 250cc win. Fonsi Nieto then took his first ever race win in the Spanish Grand Prix. Nieto also took the lead in the championship standings from de Puniet and Franco Battaini. Nieto then won the following race at Le Mans before Melandri won the next three races and overtook the championship lead from Nieto after the Dutch TT. Melandri continued his streak to six consecutive wins and extended his lead in the standings to 37 points after the Czech Republic Grand Prix.
Nieto won the Portuguese Grand Prix for Aprilia's tenth consecutive victory. Nieto, who crashed in lap 13, recovered from seventh position to win the rain-soaked race over Melandri. Aprilia's winning streak was broken when Yamaha's Sebastián Porto won the Rio de Janeiro Grand Prix under wet race condition. Rookie Toni Elías won the following race at Motegi after a last-lap battle with Melandri. Melandri finished second and increase his lead over Nieto in the championship standings to 52 points. With 52 points lead and three races to go, Melandri only need to finish in front of Nieto in the Malaysian Grand Prix to clinch the championship. However, he suffered a mechanical failure on the first lap, while Nieto won the race to reduce the gap to 27 points. Melandri finally clinched the 250cc title in the Australian Grand Prix with a close win over Nieto. They fought until the last lap and Melandri won the race with just 0.007 second gap at the finish line. Melandri became the youngest 250cc world champion at the age of 20 years and 74 days.
Melandri ended the season with 298 points from nine race wins, three second-place finishes and one fourth-place finish. Nieto finished second in the standings with 241 points and four wins, followed Honda's Roberto Rolfo and rookie Toni Elías with 219 and 178 points respectively. Elías, who recorded one race win and four further podium finishes, was named as the Rookie of the Year. Aprilia won the constructors championship with 382 points and 14 race wins from Melandri, Nieto and Elías. Honda finished second in the standings with 244 points but failed to record any race win. Yamaha, who won two races courtesy of Miyazaki and Porto's wins in the wet, finished third with 211 points.

### 125cc class

The 125cc entry list was headlined by defending champion Manuel Poggiali and two-time championship runners-up Youichi Ui and Noboru Ueda. There were five other riders who have previously won a 125cc race: Masao Azuma, Lucio Cecchinello, Stefano Perugini, Simone Sanna and Arnaud Vincent.
Arnaud Vincent, who returned to Aprilia after a year with Honda, won the opening race at Suzuka under wet condition. He then extended his lead in the championship with two second places in the second and third race behind Manuel Poggiali and Lucio Cecchinello respectively. In the following race at Le Mans, Cecchinello won his second successive race ahead of Poggiali, while Vincent finished fourth. Poggiali then took over the championship lead from Vincent after winning the Italian Grand Prix. Poggiali won the following race at Catalunya with a late overtake at the finish line over Spanish teenager Daniel Pedrosa. Two weeks later, Pedrosa bounced back to win his first ever race in the 2002 Dutch TT, with Poggiali finishing in second place.
Vincent, who led the championship in the first four races, returned to the top of the podium with two consecutive wins at Donington Park and Sachsenring. After finishing third behind Cecchinello and Pedrosa at Brno, Vincent won the wet Portuguese Grand Prix and retook the championship lead from Poggiali. Honda riders, Masao Azuma and Pedrosa, won the following two races at Rio de Janeiro and Motegi while Poggiali reduced Vincent's lead to just eight points courtesy of two podium finishes and Vincent's mechanical problem at Motegi. Vincent extended his lead by winning the Malaysian Grand Prix while Poggiali finished in fourth. However, Poggiali won the following race at Phillip Island while Vincent finished in fourth to reduce the lead back to eight points. In the last race of the season at Valencia, Vincent finished second behind Pedrosa to clinch the 125cc title while Poggiali finished in seventh place.
