A review of 70 years GP : the Seventies

 

The 17th edition of the A-XOC Bikers'Classics - which will take place from July 5 to 7 - will focus on a major anniversary: ​​the 70th anniversary of the Grands Prix moto. The opportunity to look at the history of GPs. Chapter 3: The 70s.

Like the end of the sixties, the beginning of the seventies is marked by the domination of one man, Giacomo Agostini, who will eventually abandon MV Agusta in favor of the Japanese manufacturer Yamaha in 1974. To follow are two new titles for King Ago: 350cc in 1974 and 500cc in 1975, bringing its total to 15 world crowns, a record that is not about to be beaten ...

This 500cc title in 1975 on a Yamaha also marks a turning point in the history of the Grand Prix as it puts an end to the hegemony of MV Agusta on the queen category. Until then, the Italian brand has been winning the manufacturers title continuously since 1956 (with the exception of the years 1957 and 1966). From that moment on, MV will be only entitled to the crumbs left by the Japanese manufacturers.

Other brands still try their luck, mainly in the lower categories: Bultaco, Kreidler, Morbidelli, but also Harley-Davidson. It is often forgotten, but the American brand has won twice in the 250cc championship reserved for Manufacturers (1975 and 1976), with rider Walter Villa who also won several titles in the riders championship as from 1974, and a title in 350cc (1976). At the time, Harley was associated with the Italian brand Aermacchi, which probably explains this ...

Increasingly powerful and faster, the machines reach crazy speeds, making the 'old' circuits more and more dangerous for bikers, especially the ones with the crash barriers installed for cars. In Francorchamps, the construction of a new circuit was decided in September 1976. It will be finished for the Grand Prix of 1979. Meanwhile, Barry Sheene (Suzuki) signs the fastest lap (in race) of the old circuit at an average speed of 220,720 km/h. A year later, Johnny Cecotto makes a lap of 222.362 km/h during practice ... The new circuit will be inaugurated in time to welcome the 1979 GP, but its surface is considered too slippery in case of rain, and most of the top riders decide not to start.

1976 is also the year when the Tourist Trophy has to say farewell to the Grand Prix. The too dangerous 'mountainous' circuit is replaced on the calendar by Silverstone. The last winner of the GP of the Isle of Man is the Irishman Herron on a Yamaha. He completed the four laps of the circuit (nearly 243 kilometers) in 1h27'26''80. At the time, races were usually completed in less than an hour ...

For the first time, in the late seventies, an American riders shines at the top of the world hierarchy. Kenny Roberts dethrones the British Barry Sheene (titled in 1976 and 1977) and takes the lead of the queen class until the beginning of the 80's ...
