From Wikipedia, the free encyclopedia
Barry Sheene (pictured in Assen next to Wil Hartog) became the 1977 500cc world champion

The 1977 Grand Prix motorcycle racing season was the 29th F.I.M. Road Racing World Championship season.

Season summary

[edit]

Suzuki rider Barry Sheene won six of ten rounds in 1977 to successfully defend his 500cc World Championship as the Suzuki RG 500 continued to dominate the championship.[1] Virtually every privateer team chose to compete with the production version of the Suzuki motorcycle.[2][3] The 1977 season marked the first time in Grand Prix motorcycle racing history that the Isle of Man TT was not part of the World Championships, as the event was moved to the Silverstone Circuit after a protracted rider boycott over the safety issues of the Isle of Man TT Mountain Course.[1]

The season was marred by a serious accident at the 350cc Austrian Grand Prix race that claimed the life of Swiss rider, Hans Stadelmann and seriously injuring several other riders.[1] The accident exposed a lack of medical assistance and led to a rider's strike.[1] The incident highlighted the increasingly acrimonious relationship between competitors and race organizers over the lack of safety at race meetings.[1]

The British-based Heron-Suzuki team served as the de facto factory team in the 500 Class with Sheene as their top rider.[4] John Newbold and John Williams were released from their Suzuki contracts at the end of the 1976 season and replaced by Pat Hennen and Steve Parrish.[1] Hennen was promoted to Suzuki's main team after an impressive rookie season in 1976 during which he became the first American competitor to win a 500cc Grand Prix race, while Parrish had won the 1976 ACU British championship.[5][6]

Yamaha returned to the World Championships after a one-year hiatus, providing new motorcycles for three satellite teams. Fifteen-time World Champion Giacomo Agostini's Marlboro-backed team, Johnny Cecotto's Venemotos team, and Steve Baker's Yamaha of Canada team all received the latest version of the Yamaha YZR500.[1][7] Cecotto was the 1975 350cc World Champion, while Baker was making his World Championship debut after having won two AMA national races in 1976 as well as the prestigious Mallory Park Race of the Year.[8][9]

Sheene established his dominance at the season-opening Venezuelan Grand Prix with a victory over Baker and Hennen.[10] Baker showed that he was a contender for the title by sharing the fastest lap time of the race with Sheene in just the first Grand Prix race of his career.[11]

The second round at the Salzburgring circuit in Austria was marred by crash during the 350cc race that claimed the life of Swiss rider, Hans Stadelmann and seriously injured Johnny Cecotto, Patrick Fernandez, Dieter Braun and Franco Uncini.[12][13][14] The lack of onsite medical facilities exacerbated the situation and exposed the race organizers' callousness and indifference regarding the safety of competitors.[14] Sheene and most other 500 class riders refused to race, despite the race organizers offering riders double the usual start money.[14] The race organizers pressed on with the race as Jack Findlay won from a reduced field of competitors.[12] Cecotto sustained a broken arm in the accident and missed five rounds while recovering from his injury, while Braun decided to end his racing career after recovering from his injuries.[15][16]

Sheene continued to set the pace with another victory at the German Grand Prix ahead of his Suzuki teammate Hennen in second as Baker finished in third place.[17] At the fourth round at the Imola Circuit in Italy, Sheene won again while Virginio Ferrari scored an impressive second place for the Roberto Gallina-Suzuki team.[18] Baker finished fourth behind Armando Toracca (Suzuki), while Hennen crashed out of the race when a newly designed fairing he was using touched the ground.[19][20]

Baker claimed the pole position at the 500cc French Grand Prix, but he was unable to stop Sheene from winning his third consecutive race.[19][21] At the age of 35, Giacomo Agostini showed that he was still competitive when he finished the French Grand Prix in second place ahead of Baker in third place.[22]

Wil Hartog (30) in action during the 1977 500cc Dutch TT.

Wil Hartog made history at the 1977 Dutch TT when he became the first Dutchman ever to win a premier 500cc Grand Prix.[23][24] His Suzuki teammates Sheene and Hennen finished second and third.[25]

Sheene's victory in the 1977 Belgian Grand Prix marked the fastest motorcycle Grand Prix race in history with an average race speed of 135.067 mph (217.369 kph).[14] The following year, the Spa-Francorchamps road course was replaced by a shorter, safer track, meaning that Sheene's record could never be broken.[14] At the following round in Sweden, Sheene clinched the World Championship with his sixth victory of the season. Johnny Cecotto returned from his injury to finish the race in second place, 2.9 seconds behind Sheene while Baker came in third place.[26]

Cecotto won Round 9 in Finland ahead of Marco Lucchinelli and Franco Bonera, with Sheene finishing in sixth place as his Suzuki overheated.[11][27] Baker faltered in twelfth place with spark plug problems, while Hennen failed to finish when his motorcycle's clutch failed, ruining his chances of finishing the championship in the runner-up spot.[11][20] Cecotto won again in Czechoslovakia where he scored a double with victories in both the 350 and 500 classes.[8] Agostini scored another second-place result in Czechoslovakia ahead of Michel Rougerie and Hennen.[22] At the final race of the season in Britain, Sheene was leading the race when he was forced to quit with a mechanical failure which allowed his teammate Parish to claim the lead ahead of John Williams with Hennen in third place.[28] As they began the final lap, Parrish crashed out of the lead, and then Williams did the same three corners later, handing Hennen his second career Grand Prix victory.[20][29]

Sheene and Suzuki dominated the season by winning six of the first eight races, to finish well clear of Baker in second place.[30] In just his first season in World Championship competition, Baker ranked second despite never having raced in the rain before and having no prior knowledge of European racing circuits.[11][31][32] He also had no previous experience with the FIM regulations that required races to be started with dead engines, making competitors push start their machines.[33] Baker's Yamaha did not start as easily as the numerous Suzuki riders surrounding him meaning that he usually began most races behind his competitors.[33] Despite finishing second to Sheene in the 500 Class and winning the Formula 750 championship, Yamaha only offered Baker a contract to compete in the American national championship in 1978.[11][31]

Hennen finished in third place for the second consecutive year despite facing animosity from his Suzuki teammate Sheene. Sheene recognized Hennen as a threat to his position at the top of the team's hierarchy and reacted by commandeering the best equipment for himself.[34] Cecotto's late season victories vaulted him into fourth place ahead of Steve Parrish in fifth.[30]

Giacomo Agostini failed to win a Grand Prix for the first time since 1964.[22] In the final season of his accomplished career, he was still competitive with two second place finishes in the 500 championship and another second place in the 350 championship.[7] Agostini ended the 1977 season ranked 6th in the 500 class and 16th in the 350 class.[22] He won the final race of his career on September 25, 1977 at the final round of the 1977 Formula 750 Championship held at the Hockenheimring.[7] Agostini then announced his retirement from motorcycle competition at the age of 35, having scored 159 podiums, 122 Grand Prix victories and 15 World Championships.[22]

After losing the 350 World Championship to the Harley-Davidson team in 1976, Yamaha reclaimed the title with Takazumi Katayama riding a unique, three-cylinder motorcycle developed at Yamaha's European headquarters in the Netherlands by Ferry Brouwer, Trevor Tilbury and former 125 World Champion, Kent Andersson.[35][36] Katayama won five races during the season, far outpacing second placed Tom Herron (Yamaha).[37] Katayama's victory marked the first time that an Asian competitor had won an FIM World Championship.[38]

Morbidelli factory rider Mario Lega won the 250cc World Championship, ending the three-year reign of the Harley-Davidson-owned Aermacchi team and their rider Walter Villa.[1] The season was one of the most competitive in years with seven different race winners in the first seven races of the year. Lega began the season as a substitute rider, filling in for the injured Paolo Pileri, the 1975 125cc World Champion.[39] However, after his surprise victory over Takazumi Katayama at the 250cc Yugoslavian Grand Prix vaulted him into the championship points lead, team owner Giancarlo Morbidelli asked Lega to remain on the team for the remainder of the season.[39] When Mick Grant won the 250cc Dutch TT for the Kawasaki team, it marked the fourth manufacturer to claim a 250 class victory in 1977 (Harley-Davidson, Yamaha and Morbidelli were the other three).[1] Lega scored three more podiums to clinch the 250cc World Championship ahead of Harley-Davidson teammates, Franco Uncini and Walter Villa.[1] Eight different competitors claimed victories during the season.[1]

Morbidelli rider Pier Paolo Bianchi successfully defended his 125cc title with his teammate Eugenio Lazzarini finishing second.[1] His victory made for an impressive double World Championship in the 125cc and 250cc divisions for the tiny Morbidelli factory.[1] Angel Nieto won his third consecutive 50cc title while riding for the Bultaco factory team.[1]

In addition to crash-marred Austrian Grand Prix, the Yugoslavian Grand Prix at the notorious Opatija Circuit was also stricken by tragedy. After having been issued an ultimatum by the FIM, the Yugoslavian race organizers failed to take action to improve the safety of the circuit – which was notorious for its numerous road-side hazards including solid rock walls and steep, barely protected drop offs.[40] The event was a disaster with Italian rider, Giovanni Ziggiotto, crashing during practice for the 250cc race when his motorcycle's engine seized and he was hit from behind by Per-Edward Carlson.[41] Ziggiotto died four days later in a hospital.[42] During the 50 cc race, Ulrich Graf crashed when his bike developed a rear tire puncture and he was thrown into a stone wall.[41] He suffered serious head injuries and died later in a hospital.[40] The Opatija Circuit was never used again for any kind of racing and, the Yugoslavian Grand Prix was moved to the nearby Rijeka permanent circuit.[41]
