Roberts' eight podiums and four wins (from ten Grands Prix) during his first season in '78 - where he also competed in four 250cc rounds taking four podiums - still ranks as one of the best rookie campaigns of all-time. Roberts enjoyed era-defining rivalries with the likes of Barry Sheene and Freddie Spencer before making a successful move into team management where he continued to bring trophies to the Iwata hallways by overseeing countryman Wayne Rainey's ascension and eclipse of his achievements. The vitality of Kenny's competitive 'genes' were put beyond doubt when both of his sons, Kenny Jnr and Kurtis, became MotoGP racers; the former taking the penultimate 500cc championship in 2000. 24 wins (at least two in each of his six seasons), three championships as a rider, three as team manager underpin his profile as one of the GP's flagship stars. As champion, ambassador, pioneer, trend-setter and Yamaha legend, Kenny Roberts is still one of the company's most famous road-racing sons.
