After a few years top riders like Bicker (who rode Cz), John Banks( BSA to Cz), Brian Goss (Greeves to Maico), Bryan Wade (Greeves to Husqvarna), Vic Allen ( Greeves to Maico) were riding foreign makes. It was stil clubman racers who could not afford the new machines that rode the British machines.
As the years went on and the Japanese Suzukis took over the races, Belgian Joel Robert became World 250cc champion six times, along with compatriot Sylvian Goebers as his team mate in second. In the 500cc class Roger De Coster, also Belgian held the crown for five years. Despite the constant challenge of the East German Maico and the Czech Cz machines.
By this time, even clubman racers had got the Japanese machines, a few stalwart riders like Dick Clayton for Greeves and Vic Eastwood for AJS stayed true, but even they went to foreign makes as the British machines could not compete with mass produced Japanese bikes. Clayton went to the Swedish Husqvarna firm. After trying a few seasons for Maico, Vic Eastwood rode for Alan Clewes CCM firm, which was a rebuilt BSA bike.
