LAS VEGAS — Robbie Knievel, an American stunt performer who set records with daredevil motorcycle jumps following the tire tracks of his thrill-seeking father — including at Caesars Palace in Las Vegas in 1989 and a Grand Canyon chasm a decade later — has died in Nevada, his brother said. Robbie Knievel died early Friday at a hospice in Reno after battling pancreatic cancer, Kelly Knievel said. But where Evel Knievel famously almost died from injuries when he crashed his Harley-Davidson during a jump over the Caesars Palace fountains in Las Vegas in 1967, Robbie completed the jump in 1989 using a specially designed Honda.
