This Dirt Track Yamaha XS 650 racer is one of the bikes used by King Kenny on his way to winning the 1974 AMA Championship and becoming one of just four riders (the second at the time) to complete the AMA Grand Slam, a feat he would complete in a single season the following year.

Fresh from his 1973 championship win, Roberts would defend his title and take the ’74 championship in comprehensive style. He scored points in every round and piled up six wins and thirteen podiums to beat his ’73 record with huge haul of 2,286 championship points.

He used this XS 650 on Short Track, Half-Mile and Mile events, claiming two wins and a further six podiums on it. It is authentic, complete and has been preserved in the immaculate condition in which it finished the 1974 season.
