Sheene's battle with Kenny Roberts at the 1979 British Grand Prix at Silverstone has been cited as one of the greatest motorcycle Grand Prix races of the 1970s. After the 1979 season, he left the Heron-Suzuki factory team, believing that he was receiving inferior equipment to his team-mates. He shifted to a privateer on a Yamaha machine, but soon started receiving works equipment.
A virtually unknown Wayne Gardner came from Australia to race in England in 1981. He raced the Moriwaki Z1000 and slept in his car. Towards the end of season he went to Olivers Mount, a public road/park circuit in Scarborough, and beat former two-time World Champion, Barry Sheene, who was on a factory Yamaha GP bike. I'm assured that's Bob Smith tucked in behind Sheene.
