OK, anyone out there who skis and has been down or even just checked out a downhill ski course knows how steep and treacherous they can be. Going down is enough to get your heart rate going...but have you ever imagined trying to ride a motorcycle up the course—with snow and ice on it? No? That makes two of us. But leave it to the crazies at Red Bull to cook up an imaginative stunt where three-time MotoGP World Champion Marc Marquez rides a Honda RC213V MotoGP bike equipped with tires studded with two-inch-long ice spikes up a fabled Alpine downhill ski course. The Hahnenkammrennen course on the Hahnenkamm peak near the ski resort of Kitzbühel in Austria is known as one of the toughest on the World Cup skiing circuit, and Red Bull had Austrian ice speedway legend Franky Zorn install ice racing spikes on some sport tires that would fit the actual RC213V MotoGP machine (it may have been an S version with the race kit, and some of soundtrack has an engine that sounds like a CBR, probably from practice runs) that Marquez was slated to ride up the course.
