His British Grand Prix victory aboard a Suzuki RG500 marked the last time a privateer competitor would win a 500cc Grand Prix race, as motorcycle Grand Prix racing became increasingly professional during the 1980s. His best years were in and 1981, when he finished in seventh place in the 500cc world championships.
