Runningmom - I've raced anything with two wheels for a long time. In fact I've raced Kenny Roberts Jr. at the Lodi Bowl before he became World Champ.
I still race 2-3 times a year and do as many trackdays as I can. But trust me, I can't hustle a bike around a track like the guy in the video. That's hauling some serious ass on a road course with guard rails. Reminds me of the Isle of Mann TT or Manx GP true road races.
