AMERICAN NEWS channel KSBW has covered the build-up to this year's USGP at Laguna Seca, including a star-studded kart race featuring GP riders past and present.

Watch as Eddie Lawson, Wayne Rainey, Kenny Roberts Snr. (what's with the hair, dude?) and current MotoGP World Champion Valentino Rossi lay down the rubber in super-fast two-stroke racing karts.

Reports say the karts are just a couple of seconds a lap slower than the MotoGP racebikes! And in the second video, you cansee the super-talented Rossi leading the old guys into the final turn.
