Hey everybody got to ride ktm quads both sx and xc it was my first time on the sx, now I'm not a racer or anything like that but I'm use to handling a machine with with alttle more power I ride a 558 predator is it just me or is the 505 a dog gone rocket ship that thing just flat out hauls the mail and I mean that thing would get it. The suspenders where like riding on steel wheels jar you to death It didn't take long for arm pump to set in + all that power = me very tired quickley. I want that motor for the woods I just love the hit that thing produces I gets my blood flowing. My question is how much better is the xc over stock with a pipe and how much better is the sx with pipe over stock? Oh yeah did I mention that the sx handled like a f1 car ktm has taken stock atvs to the next level. Thanks ktm for putting on such a good demo memorys I will always hold with with me that I shared with friends and family.
