The 1972 Grand Prix motorcycle racing season was the 24th F.I.M. Road Racing World Championship Grand Prix season. The season consisted of twelve Grand Prix races in six classes: 500cc, 350cc, 250cc, 125cc, 50cc and Sidecars 500cc. It began on 30 April, with West German Grand Prix and ended with Spanish Grand Prix on 23 September.

Season summary

Giacomo Agostini's reign as the 500cc World Champion continued in 1972 with the MV Agusta rider winning his seventh consecutive title by claiming a record 11 victories in the 13-round series. His record stood until when Mick Doohan won twelve races. Agostini's MV Agusta teammate, Alberto Pagani finished second to Agostini in most of the rounds. By 1972, MV Agusta was the last major manufacturer to compete in the FIM World Championships using four-stroke motorcycles, as advancements in two-stroke engine technology by Japanese manufacturers were becoming evident. Kawasaki returned to the World Championships, providing machines for Dave Simmonds and Eric Offenstadt. The Yamaha factory won its first-ever 500cc Grand Prix race at the season ending Spanish Grand Prix at Jarama when Chas Mortimer won the race after Agostini sat out the event after already winning the championship,

The 350 class proved to be more of a challenge for Agostini where he faced strong opposition from Yamaha rider, Jarno Saarinen. At the season-opening German Grand Prix held at the daunting Nürburgring race track, Saarinen defeated Agostini for the first time in a head-to-head race. It also marked the first time that Agostini had lost a race since the 1967 Canadian Grand Prix. Saarinen also won the 350cc French Grand Prix and scored a double victory at the Czechoslovak Grand Prix with victories in both the 250cc and 350cc classes. Agostini would eventually prevail to clinch the 350 title with six victories however, the threat from Saarinen's two stroke Yamaha was so strong that the previously dominant MV Agusta factory was forced to produce a new 350cc motorcycle for Agostini.

The 1972 250cc World Championship began with four different race-winners, (Hideo Kanaya (Yamaha), Phil Read (Yamaha), Börje Jansson (Maico), and Renzo Pasolini (Aermacchi), however Saarinen led Pasolini in the championship points race due to his consistent results. After Barry Sheene was injured at the 250cc Nations Grand Prix, his specially made, factory-supported Yamaha YZ635 was given to Saarinen."Ikuisesti nuori" by Arto Teronen - , p.145 Saarinen rode the special Yamaha to win four of the last six Grand Prix races to clinch the 250cc World Championship by a single point over Pasolini. Angel Nieto claimed a double, winning the 125cc and 50cc championships for Derbi before the Spanish factory announced its withdrawal from Grand Prix racing.

This would be the final season for the East German Grand Prix as a championship race, as SED officials, troubled by fans singing Das Lied der Deutschen (the West German national anthem) after Dieter Braun's victory the previous season, limited entries to only Eastern Bloc nations beginning in 1973. On 23 October 1972, Dave Simmonds was killed in a fire caused by an exploding gas cylinder in a caravan owned by fellow racer Jack Findlay while attending a non-championship motorcycle race at Rungis near Paris.

Agostini's Isle of Man TT boycott When Gilberto Parlotti died in an accident while competing in the 1972 Isle of Man TT, Agostini announced he would never again compete in the event, as he considered the 37.73-mile circuit unsafe for world championship competition. At the time, the Isle of Man TT was the most prestigious race on the international motorcycle racing calendar, and his stature as the reigning World Champion gave the announcement an immense impact on the sport.

Agostini's decision to boycott the event had far-reaching consequences for the TT and would lead to a walk-out of the top Grand Prix stars, many of whom resorted to severe criticism of the organisation and safety at the event, with people such as Phil Read in the vanguard of the critics. In response, the FIM decided that the Isle of Man TT would be withdrawn from the World Championship calendar after the 1976 races. The British round of the FIM championship was held at Silverstone Circuit on the mainland from 1977 onwards. Agostini maintained that he did not object to the event itself, but that he only opposed riders being contractually required to enter such a dangerous race as part of a World Championship campaign.
