American legends, Wayne Rainey, Kevin Schwantz, Eddie Lawson and Doug Chandler will not only be in attendance at Laguna Seca, but will also be featured as a support race for the event.

Because Dorna decided not to bring the regular MotoGP support classes, 125cc and 250cc GP, the four will compete in a World SuperKart round, which will act as a support race for the main MotoGP event.
