Hello, I found this forum while shopping on line for clamp on passener foot pegs for my 2005 525 MXC. I do not want to weld my frame, so I thought these clamp on foot pegs might work on my bike? Occasionally I need to haul a passenger, and these look like they might be very handy for that task!? I am on the road for the next couple of days and my KTM is at home so I cannot measure right now. The add says the they will fit if the rectangular swing arm dimensions are not larger than 1 11/16" X 3". Here is the link to the clamp on peg add. http://www.fourstrokesonly.com/Buddypegsclampon.html Thanks in advance for any help!
