Robbie Maddison is often referred to as the modern day Evel Knievel, and the following video clearly demonstrates why. The Aussie stunt rider has a number of impressive achievements under his belt, some of which include clearing an entire football field, jumping the fountains at Caesars Palace in Las Vegas, and riding a massive wave at Teahupoo in Tahiti on a modified dirt bike. The ski jump involved launching at 115 km/h, clearing 113 m, and dropping 18 1/2 stories. Watch the madness here.
