Bubba's career ended in 1989 at Laguna Seca. So he definatly raced against Rainey, Schwantz and Lawson. I'm still digging to try and find when Mamola was riding. For a guy so involved with MotoGP he sure doesn't have career stats up very many placesMotorToad said:In the late '80s there was Rainey, Mamola, Schwantz, and Lawson. Maybe Schoebert, too? I can't find an entry list on google, but that's the most I can recall being in GP at the same time. And I'm not sure they were all there at the same time.
