The curbs at VIR have been ripping off knee pucks, tearing up riders’ leathers and injuring riders’ knees since 2001. In 2003, Jason DiSalvo’s left knee snagged the sharp leading edge of a curb during an AMA National weekend at VIR, sending him to the hospital. Last Sunday during an AMA Daytona SportBike race DiSalvo got a second dose of the curb treatment at VIR; ironically, this time he hit his right knee on a section of sharp-edge curbing one corner past where he hit his left knee in 2003. The sharp edges on the curbing in the corner DiSalvo originally had trouble with in 2003 have been ground down to resemble ramps, allowing riders’ knee pucks to glide over them. But the same fix has not been applied to all the curbs at the track, leaving more sharp edges in place for DiSalvo to hit this year. This time the impact tore his leathers and twisted his knee so badly that he ran off the track, coasted nearly to a stop and fell over in agony. Chris Ulrich hit a sharp curb edge during the American Superbike race on Sunday, ripping open the left knee of his leathers and sending his knee puck flying, leaving him to learn to race without dragging his knee but without causing physical injury. Now, for your viewing enjoyment, we present a quick look at some good curbing and some bad curbing at VIR.
