1981 Grand Prix motorcycle racing season

Marco Lucchinelli (pictured in Assen) became the 1981 500cc world champion

The 1981 Grand Prix motorcycle racing season was the 33rd F.I.M. Road Racing World Championship season.

Season summary[]

In the 500cc world championship, two Suzuki teams fought for the title with Marco Lucchinelli riding for Roberto Gallina's Italian Suzuki team and, Randy Mamola riding for the Heron Suzuki team backed by the UK Suzuki importer. Mamola started the season strongly with two victories and two second-place finishes to take the lead in the championship but then, Lucchinelli took command with four victories in the next five races to claim the world championship.^[1] Mamola finished in second place for the second year in a row.^[1]

Barry Sheene would win the final race of his career with a win in Sweden while a young American named Freddie Spencer made his first foray into the world championships as a member of the Honda factory racing team, riding the four-stroke Honda NR500 up to fifth place at the British Grand Prix before it suffered a mechanical failure.^[1]

Germany's Anton Mang scored double world championship victories, defeating defending champion Jon Ekerold for the 350cc title and, winning ten of twelve 250 events to take that title.^[1] Frenchman Michel Rougerie, who finished second in 1975 250 championship, was killed when he was hit by another rider after crashing in the 350 race in Yugoslavia.^[2] Angel Nieto won his tenth championship by winning eight of twelve rounds on his Minarelli while Ricardo Tormo won the 50cc crown for Bultaco.^[1]

Beginning in 1981, motorcycle frame technology evolved quickly as motorcycle manufacturers moved from the steel, featherbed frame chassis first developed in the 1950s, to aluminium frames featuring large, twin beams as first pioneered by Spanish constructor, Antonio Cobas.^[3]
