Taddy Blazusiak won his 4th consecutive Erzberg rodeo in 2010 riding a ktm 250 EXC. He was also on KTM 2 strokes the previous 3 wins, although I thought he was on a 300 in 09.
I forget the 2009 results, but in 2010 there were over 500 riders at the start, and only 15 to cross the finish line. Pretty insane! I think 2009 is the year pastrana rode in it. He didn't make it very far, lol.
